Just giving it back to little kev for calling out Smitty and putting down his boat. Then he names MT, DEADPEOPLEGUY and Tim in his circle jerk of "true" offshore boaters and anybody else that does not measure up with him as trash that belongs on another site.

Thats how I read it but maybe I just don't like the guy.

I always wanted a 43SC so were even.

Smitty has always been a stand up, good guy on this site!

As always, Brian brings a whole new level of class to a thread. Seriously, it reminds me of high school.

Only so he can brag about his boat....AND efi....

silly season has officially started,should be one hell of a winter!

I forgot... Stupid me lol

once again when you have incorrect facts (as you do ) you start the personal attacks. IOW, you have no brilliance to dazzle anyone with so you regressed to your usual MO of trying to baffle with BS. Why don't you check with your 2 idols straub and steelchump and check on the I/O/wet exhaust/offshore boats they have had, or better yet have. you will find a big fat zero for an answer. Oh wait, I'm sorry. straub had a rinker, but when it needed an oil change he didn't know how to do it so he sold it.

Sorry you don't like the motor that was in my boat. Guess I must not be in your money league. 637 HP doesn't count in the offshore world to you. Some of us can't write the big checks for cranks and pistons and rods etc, so we do the best with what our checkbooks allow. Guess you better tell Mercury that the thousands of 525's they have sold are nothing.

[QUOTE=ICDEDPPL;4376350]Aww don`t cry, btw, it was Clown Zone that crawled from under his rock to defend Butt Hurt Bobby, as usual.

Here he is.. still boatless. Had one had a bad ass 502 thou once thou so watch out! :lolhit:

Well it's interesting that Kevin likes a post in which you proceed to call me names! I guess that must make it official that he has joined the Chicago Clown Posse. That's too bad! ICDEDPPL, I see you are as mature as ever. You must be real proud that you can find silly pictures on the internet and repost them

Also, I 'm quite curious how I am without boat? I boated all summer, and my engines ran perfectly. Especially after I ripped those garbage Reed cams out of my engines that your buddy sold me. With that change alone I picked up 4 mph. Keep it coming- you are just showing what you don't know!

Again I responded to insults from little kev about another member and his degrading of that members boat. Just like clock work the little pr ck came on with a big speech and is going to let his group of hate (which you seem to be following) go after everybody that disagrees with them. He will not post again just post "likes" after he starts the fight....I think we all had a kid in school like that. You being fresh out of HS should have some friends that do this. What year did you go into business, best I can tell it was before you were born.......maybe daddy got you going.

By the way lets be honest here, little kevs engines only showed a touch over 730 HP on the dyno with somebody else's carbs and are less now that they are in the boat. Good job team struab you almost reached 750 HP with dry exhaust!!!!!

Will a 1000cfm throttle body support 650hp? 1000' ASL

Whats with your obsession about Kevins size ? You love calling him "little". I dont see him calling you "tubby, slob, pregnant transvestite, mrs doubtfire, michelin man" or any of that. Youre gonna say "kristy" is a little too thin for your liking !!!??? You refer to straub as cslob!!???

As far as your dyno information , maybe kevin or his buddy who dynoed them can clear that up.

Now youre gonna jump on retter ? Why? Because while your being coached on how to build a 572 by several avenues, ryan is building twin turbo marine LS engines, without the need of help from an "engine developer"?

[QUOTE=endeavour32;4376446]Lol, the only garbage is that formula with all the junk used parts you have purchased. Funny, you were real happy at the time to get a pair of used hydraulic roller cams, and hydraulic roller lifters for pennies on the dollar, because you couldnt afford to buy proper new stuff.

Oh, and those reed cams youre talking about, came from your west michigan buddys... kaaama mark, then to dave ritter, and made 700hp in some 509s with a 250 blower, and some stock iron merlin heads, and ran for many years ...i gave them to you for 75 dollars per cam, and 150 dollars for a set of good used hyd roller lifters ....75 bucks for a roller cam! And you got the nerve to come on here and say i sold you garbage...lmao!

So, lets see, you had those cams in some stock 420hp 454s (which anyone would know is a decent upgrade over the stock flat tappet), and now replaced them, with some bob cams, and afr heads, raised compression, and are bragging about how you gained 4mph by getting rif of those "garbage" reed hydraulic rollers?? How much did that cost ya to gain 4mph

I have come on here for 2 years defending 3 business's from little kev that hits and runs like a punk terrorist that as of late YOU and YOUR buddies fight the rest of his battles.

As far as Ryan goes this is the 4th time he has come out against me without me ever mentioning his name or his business, my FIRST strike back. Did not need Ritter got all I need from his web site and facebook.

Cslob has been a name given to straub on MANY sites for MANY years not something I made up. His failures are documented all over the web, being a copy and paste guy I am sure you have run into a few.

Im sure you know the answer to this, being related to someone from johnson lifters. Can you enlighten us, on the test that was performed, between the morel lifters vs johnson lifters , being the reason bob now exclusively sells the johnson lifters ? All i heard was "the johnsons left the morels in the dust " or some vague statement like that. I spoke to a couple distributors for morel, and they too would like to know more about this test, what it consisted of, etc. I see bob is no longer listed as a dealer for morel lifters. Just curious, because at one point bobs major selling point when he was pushing the morels, was their .750 wheel , and now, he is selling lifters with .700 wheel. Alot of us purchased morels thru bob thinking they were the best lifter on the market according to him, so i am interested in how the johnsons outperformed them.

It's fun watching Brian get all worked up further hurting his own business on a daily basis

He doesnt need oso!! Dont you know that!

Apparently though, he does need a coach to help him pick out which heads, which lifters, design a cam, valvetrain, and so on.

I remember when there was a time, an engine builder, spec'd his own parts, and didnt need someone to pick them out for him based on some computer simulations, they actually learned through years of experience and dyno testing. They wrote the book, not just read the book. And yet, im the guy who regurgitates info i read ?? Hmmm, and going to pri and Advanced engineering conference to listen to others speak, is so different ?

I got an invite from another oso professional to attend this year with him. I will not say his name, because i know if the "clan" finds out he invited me, he will be put in the black book as well. Plus, not sure i would want to go, and have "big" brian hit me with a baseball bat, like he said he is gonna do to you

Brian,

I merely made an observation regarding your level of professionalism. Not only do you continue to sound juvenile with your attacks, but continue to degrade your and your company's image.

Young man I have 35+ years in this business on you so look me up when you reach that pinnacle. I am not worried in the least what YOU or your copy and paste internet engine guru's think about my business as we will never do any. You have been hounding me for the past couple of months and I see now that it comes from the Chi-town duo, little kev and Tim group that worship you and Cslob now as another business owner heed your own advise and quit coming after me unless this is a game you enjoy.

I love how much you post my name=obsession...

So at what hp level do you feel the 310 or the common AFR 305 heads should be changed to something else and make a nice noticeable bang for the buck improvement in hp on a 540?

I figured I'd at least ask, you never know. We should occasionally try to get back on topic.

The heads will support somewhere in the 800hp range with the right combination. HP really doesn't play into the factor but more RPM and displacement, and where you want to make peak power. The more displacement, the less rpm a given head will handle. I'd say for a 540, if you're trying to make power much above 6000rpm, you would want to at least do an intake valve upgrade to a 310-315cc head, but don't necessarily need a "bigger" head. The port can handle plenty of air but the valve becomes the restriction. A set of 310-315cc heads with a 2.30 intake valve make a nice combination on a 540 running above 6000 rpm. Of course, by the time you blend the bowls and shape the short turn for the larger valve, you'll pick up a few cc's of volume so "technically" they won't be what they started out as, but the cross sectional area of the front of the port will be the same. Just installing a larger valve without doing the follow up work would gain less but still be an improvement. The 2.25 valve is good to about 6000rpm peak power on a 540.

Well let's get more specific. I had a 540 making 660 hp at 5600 with 305 AFRs and a nice mild cam, Vic Jr- 4150. Now that I'm rebuilding and engines are 548, what would be the best bang for the buck improvement? I'm thinking the entire induction package I have is getting marginal for hitting 700 hp at a reasonable boat friendly rpm.

What were the old cam specs ?

And another question would be, how much of a speed increase, will 40hp per side gain in your 38 scarab, and how much will it cost overall

It depends on which 305 to 315 cc head your talking about and what RPM you plan on spinning the motor. Heavy boat vs light boat comes into play with best torque curve for the application. I suggest you give Eddie Young or Scott Foxwell a call to talk over the details of your combination. Its all a compromise and your only as good as weakest link.


Sorry I type too slow. Good info above

I'll get back to you in a minute with cam specs. The heads are AFR 305s. I'd like to keep the max rpm at 5800. It's a light boat and the old engines were over 600 ftlbs for the whole sweep. The speed increase and costs are what I'm currently struggling with. Trying to figure out what parts I should change out while I have the opportunity. The old engines were put together for a much different type of use than what I ended up using them for or I would have made different choices originally * don't seem to have cam specs on the phone. They were roughly .640/ .240

Heavy boat? Keep the TQ my new engines have yet to push my boat faster then old engines that were supposed to be 100hp less a side ....light boats run off HP, heavy boats need the big TQ numbers to carry it

Your induction is plenty for 700 hp @ 5600. The rpm is the issue. HP is air and fuel. Your 548 at 5600 is only moving X amount of air. You can't change that. You just have to use the air/fuel that you have available in the most efficient manner. I'd look at the cam and make sure everything else is spot on. Lot of power to be had in good machining and cylinder finish/ring seal. AFR 305's are an "as cast" head which means there are inconsistencies from port to port. Some of that can be taken care of on the porting bench but you don't need any bigger ports and you really don't need more airflow. The devil is in the details when you start trying to maximize efficiency.

Now lets assume I was able to change some parts. How much of a difference would it make powerwise to optimize everything based on 305s vs say 315- 320- 335?

About the same as me changing a few things to find 30-40 hp that in the end won't make much if any difference in speed... I very well know engine builder here told me to stick with my combo even though I am not too happy because te cost to change certain things at this point are not worth the gains..

You really keep missing the point don't you. Your expertise is in name calling and stupid picture posting. I don't know or care if you know them or not. These clowns that you seem to think can make good HP use dyno numbers @ 20% or more correction, and they use them in CARS. You do understand that a high HP CAR engine is not going to work in a boat don't you? If its wet its gonna revert, and the part specs that are needed to get a boat on plane and running are not even close to what you need to run a drag car or a street car.

305's will support a 540 but you are at the edge of where you want to be. If you have the money, the 315cnc's are going to be a much better choice. Assuming of course that you have the airflow from the carb or efi and the cam to take advantage of the heads. AFR can do some additions to the 305's to make them a bit better than the basic ones, again depending on the dollars you have to spend. You can call AFR and ask them for specifics. I'd tell you who else to call, but then some people on this thread will get into name calling which won't help you.

How would you explain, all the guys on yellow bullet, chevelles .com, performance boats, etc, that have bought parts from these guys, and dyno'ed at THEIR OWN facility, in various parts of the country? I could probably post up about 50 links to threads of their customers who have good feedback.

Get over yourself with this "marine" thing, as if its some secret society of how to build a "marine" engine. Sure, you run a little wider ring gaps, little more piston to wall, maybe a little more bearing clearance, maybe a little more guide clearance, wider valve seats, possibly a very mild low overlap cam if running "wet manifolds" and a little more conservative tune up. Some of the BEST marine engine builders, started out building drag race engines many decades ago. And I'm not talking about 637hp 509s'. Guys who daily put together 1000 plus HP builds and idle like stock 525's. The fundamentals still apply, whether its airflow, induction, chamber design, boost, stroke, etc

You keep talking about REVERSION. Is that all you have any knowledge about? Why, because straub sold a cam for guys boat engine years back , and it reverted water? Get over it already. When you do get another boat someday, look into dry tailpipes, so you don't have to crutch your engine with the fear of "reverting" with a lame azz camshaft. They came out in the 70's, and just about every company selling marine performance exhaust, will extend the risers for a reasonable fee, or any good tig welder with some stainless tubing.

Here's a build Alex Haxby did a few years back, with AFR 305's, on a 540ci. Keep in mind, this was a 9:1 engine on 87 octane, dyno'd in full marine trim, with all accessories and marine manifolds. Dyno headers, no accessories, a little more camshaft, another point of compression, I could easily see 700hp.

Are you really this thirsty to keep drinking the kool aid? How many times are you going to list CAR sites. This is NOT a car site. Can a car guy learn to build marine engines? Sometimes. Sometimes not. If they want to understand and not think they are smarter than the guys that have been doing it for 30 years.

You just listed 5 simple things that need to be changed in a marine engine. you skipped the hard stuff, but hey sorry if you don't understand it so you can't post it. Call straub. he can tell you. Ooops wait a minute I forgot. He doesn't know how to put a carb on an engine so you better pick someone else.

You do understand that in todays world that building a 1000 HP engine that will idle is not an "oh my god" event don't you? The days of the 900SC are long gone. The marine guys that know what they are doing are doing 1500-2000 today. and they idle too.

Why reversion? do some more homework. there are dozens of straub crap cams that reverted and trashed engines. again, stop believing them and do some of your own research on a MARINE site. If you want trashed car stuff go to the Vette forum and do some searched. the trail is long and expensive.

Wet exhaust? You ever hear about noise? you may be an inconsiderate jerk with dry exhaust, but the lakes I use don't put up with that stuff. Dry exhaust sounds great till you piss off every person around you and then wonder why performance boats got kicked off yet an other lake.

As to HP, sorry that you don't like 637. How about you go to a big poker run and tell all the guys running twin 525/600/700 that their engines suck because you don't think it means anything to build/run engines in that range.

Its called mufflers. I have dry stellings headers , and with gaffrig mufflers closed , they sounded like 330's with wet exhaust. They have plenty of options out there for that.

Please, I don't need a "lesson" from a guy, who doesn't have a boat, and had to have someone else build and spec his engines, about building "marine" engines. I am doing just fine in that department.

what makes you so fukking great? you are not engine builder, your posts are no different then any others.... many different factors in many different builds...Gellner built his name off CAR ENGINES.... now has a HUGE marine backing.... yep... cars.... endurance is endurance... yes there are differences but it's not things that are secrets...

Somehow, this guy isn't getting what I am saying. He keeps talking about foxwell/straub's "correction factors" being bullchit. What I was trying to say, is they have many customers who buy parts from them, or take advice, and go dyno their OWN engines, at their OWN choice of dyno, and post the results on public forums. If I bought a cam from straub, bob, mike jones, whomever, and go dyno my engine at my local shop, how in the fuk, does straub, bob, mike jones, have any influence on what the numbers are? Its not their dyno, nor are they even there!

Again, he keep saying "those are car guys", this is "offshoreonly".

He's gonna tell BCK, that going to the 315 AFR's would be a "much better choice". I've seen many times on forums, where Tony Mamo, has advised guys, to stick with the as cast head with CNC chamber version, as their isn't much to be gained by going full CNC port for the money, unless going for every little ounce of power.

I wonder how many guys have wasted THOUSANDS of dollars, because their salesman, or internet warrior, told them their parts were sub par, to what they can purchase. Only to find minimal gains, if any.

Last year, there was a huge argument, over some 454 builds, with 177 baby blowers, and AFR heads. I was beat up by the internet warriors and parts salesman, because I suggested the 305 head for that build, when they said the 265 heads would have been a better way to go. I then got yelled at by them, for contacting AFR directly with my inquiry! lmao. Anyhow, two different oso members built these combos, nearly identical , except for the heads. You know what the 305s gave up in low speed torque to the 265s? ZERO. You know what the 265's gave up to the 305's at 6000RPM? Very very little. One thing that should be considered, IF, there ever was a need or want to upgrade from a 454, to a 502, or even 540, those 305's still would have worked just fine with a blower, and be willing to bet, those 305's would stomp those 265 ovals, had it been a 502/540, with a whipple, or 10-71 on top. Neither one was a bad choice, and since the guy buying the 265's, was in need of static compression, with the smaller chambers, it made sense to go that route. Point is, neither choice was a make or break. Wanna know where the real power lie in those builds? The blower. A swap to a better blower, would be a change worth talking about, and certainly make changes on the speedo.

My general advice to BCK, would be, save your money buddy. Focus on the combination of the build, not only to make a good dyno number, but a reliable package that you could ABSOLUTELY stand on ALL DAY LONG in that killer old school larry smith scarab with #5's. Why? Because at that power level, in that hull, there is no reason you would need to let off the throttles for much. Sticking a camshaft in that is going to beat up the valvetrain, to try and make 20 extra hp, is not worth it in my opinion, and dropping the coin for the FULL CNC port versions of those heads, would be better spent on prop work, valvetrain component upgrades, or other things, that at the end of the day, make more of a difference, than what a little CFM is going to do for you at that level, in that boat. Thats just my opinion.
