Bat ???? Now you want to play baseball??? Must be hanging with MT too much.I was not the baseball player, somebody accused Dave of that which he personally told me never happened.I only agreed that it would have been a good solution to his problem. Fight he ll no that was 40 years ago when I like you are now and have nothing to lose......defend to the best of my ability and send the perp to jail.......I am all over that.

10 minutes a week to Kelly's does not make an OFFSHORE boater.......when we go for a ride its never less than 50 miles and we go across the lake and back not within eye site.

1994 32 Baja Caliber parting out to date has brought in just over $31500.00 CASH IN HAND SOLD, SOLD , SOLD with over an easy $50,000.00 yet to sell. Do you remember how YOU and the peanut gallery came on Powerboatswap and told everybody not a chance of me getting close to $30,000. Yesterday on Powerboatswap I listed the swim platform and had a picture of it on the boat which has already SOLD, SOLD, SOLD 30 other items. How did you do with your 32 Baja parts.........TOTALS PLEASE..........ya not so well!!!!! MINE IS NOT THE JUNK YOU SOLD!!!!!

OE sales so far with 1 boat and powertrain SOLD, SOLD, SOLD At $ $107,000.00 so far with the better of the 2 boats and way better trailer still left to sell.

So I must ask now that you are part of the Cig #1 club do you think you can get $30,000.00 for all you have if STILL running when the time comes..............not a chance in he ll !!!!!

Copy and paste this Tim so the next time you want to use this BS you can read it first. Hahahahahahahahahah back at ya TIM


Tim see what I bought with the money.......what did you get ?

What's all this talk of 310 cc heads? Don't peanut port heads easily support over 600 HP? :drink:

Damn they are calling for snow Friday night/Saturday morning! :eek:

Hahahahah all lies Hahahahah

I know you are such a cocky big ball boater I use my boat MUCH more then a 10 minute ride, ypu know nothing about me and you did not sell the empty Baja hull for 30,000 in a day my azz...you continue to contribute absolutely nothing to Oso... you act like a child for old man

I see what you bought, glad you can show off more to make yourself even more cocky. I forget that unless you are elite you cannot be worthy of living to Brian, I seriously hope you flip that cat and fall off the earth... Azzhole

Threads like this just totally turn me off to OSO. And I am not calling names because in my opinion it is everybody involved. The signal to noise ratio is off the charts.

It's a shame there are so many excellent minds here with similar interests that can't get past emotions. It ruins something that could be awesome.

Thanks for really driving my point home Tim. :rolleyes:

X10
Too many hidden agendas, most of the pros won't say a peep anymore.

Yea well Brian has done nothing but bash me since I denied his efi he uses every chance he can, he contributes nothing but garbage to the site ... So I return the bs to him... In done just had to make sure everyone knew who he was...it only helps his ego

I concur. Makes us all look bad. It's a shame really, because some of us come here to learn and get help from others who have been there. Thanks to all who contribute, please don't leave, to the others, well.... it's cheap entertainment.

matt,i totally agree and that is why i have not been posting.seems to me like everyone has to prove a point.i know we all have our opinions but some people can,t see past that and consider anything that they don,t agree with.i used to post information to help others but when someone with no experiance wants to argue it just gets old.the tech section is not what it used to be!

So wait, it's ok for brian to post ripping me apart and I am supposed to take it? I built my own engines he always posts how stupid I am and I am not professional and have no buisness building engines... Well they are fine, mistakes yes and anyone could have and I am the bad guy idiot because I didn't listen to him being a professional, you guys are right this ins a place for us to share good and bad learnings... And I post what I LEARN and brian bashes me Fuk him and anyone who makes themselves feel better bashing a guy that does his own stuff... You do t know me, he does not either... So I post all my story for others to learn from and because I don't like brian and his butt buddy bob now I am the Dik... Yes makes sense to me... At least I didn't hide my bad experience... I am sure brian has bad ones too but would never admit or post about it... He has to keep the Mr. Perfect image going

Carry on I'm done

If two engines have different heads, then they can't be identical so that makes no sense...but we're not talking about the difference between an OEM head and aftermarket...we're talking about the difference between an AFR 305, and 315. You said the 315's would be a better choice. Just asking why.

Lots of ways to make a port flow more air. To date this year we've shipped over 100K in AFR products. I know their heads very well. I've used them out of the box, mildly ported, extensively ported...they are my first choice for a production head and I can tell you that the 315 would not make any noticeable power difference over the 305's in this situation. Airflow is not the problem. AirSPEED is. The 305 having a slightly smaller cross section is going to be favorable over the 315 on a 540 in this rpm range. If you want to talk about POTENTIAL power, of course the 315 will win over the 305. Our working relationship with AFR is first tier.

Tim, 90 % of my customers are on OSO and most know you but are not interested in coming on here and jousting with you and your circle jerk. Me I am nothing more than a pig in the mud that could give 2 chits what you or anybody else thinks, its just part of my charm . If my builds were having problems (because your certainly can't please everybody) don't you think it would be all over this site. I have been on OSO for over 15 years and have seen many come and go. I have had a few in the past that I did not get along with but they are long "Duck" gone and were only "TRICKY" for awhile. Now theres you, MT, little kev, deadpeopleguy and a few other followers that chime in when it starts getting tough for you fellas but I am sure in time the weeds will be gone and if I am 1 of them so be it.

As for you........your never done...........you have a BIG MOUTH and love to make your little cartoons and insults.

























Wait for it.........................here it comes..................................1 more last word from Tim..................I am done!!!!!!

Not sure what you're talking about here. I spent a good part of this year doing port development for the GM Duramax head. We've worked directly with Rick and Chris Sperling at AFR and they have digitized and will be doing all the CNC work for our Duramax program. I have the greatest respect for Mr Sperling and his son, their products, and the operation and level of professionalism they have at AFR.

I will also say that I learned something recently and have to make a correction on a statement I made in another thread. Someone had mentioned an "inspection report" from AFR on their heads and I made a comment "no such thing". Well, that was an assumption on my part and I have to stand corrected. Evidently AFR will provide inspection reports on their cylinder heads...another feather in their cap in regards to how well they will stand behind their product.

Hahahah well that's surely true .... Have a good day hoss

You missed the point. Thats why I said "WITH THE CORRECT PARTS". If you build an engine that is designed to run with 305 AFR's, and you slap on a set of 088's, what is going to happen?

Which is the exact thing I said. I wish you guys would read the entire post not just the part you want to. If I want to build a 625 HP 540 I don't need 315's

then its improved since you told them their heads were junk. and I just don't have the time to find the thread elsewhere that you said it in your big fight with them.

See you can be nice.......aaaaahhhh, you have a nice day yourself.

If you want to build a 700hp 540 you don't need 315's. If you want to build an 800 hp 540 you don't need 315's.

If I design a 540 to run with 305's and slap on a set of 315's, what's going to happen?

Here's your quote:
I simply asked WHY the 315's will be better.
Answer: they won't. There is no advantage to throwing a set of 315's on a 540 that's trying to make power at 5600 rpm, or even 6000 for that matter. I don't care what cam, what carb, what EFI you have to provide "enough airflow"...just because the 315's flow more air doesn't make them a better choice. Heck, why not a set of 357's? The 305's already flow more than enough air and have enough cross section for 7000 rpm. Honestly, a set of 290 ovals would be a better choice. Much more appropriately sized for a 540 peaking @ 5600 rpm.

If you want to build a 540 that is going to spin over 6000 which is what you are going to need to get 800 HP, and you want to put 305's on it, have at it. The restrictions that the 305 is going to cause are huge. Not to mention, we are talking boats here, not cars. a totally different world.


well duh, you designed it to turn lower rpm's. why would you put 315's on it?


Well sure they do if you want to leave HP on the table.


you just dropped RPM from 7000 to 5600. Which is it? one size doesn't fit all. Or maybe you should sell AFR on this and they can't stop making all different sizes of heads, because you said they don't need to.

and yes, I know what I typed. which to anyone but you means that the engine is going to be spun and make HP. Last I looked the same cam that makes 650 HP in a 540 won't work to make 750 or 800 HP.

You know, you can get good look at a T-bone by stickin your head up a bulls ass, but wouldn't you rather take the butchers word for it :D

What restrictions?
Please explain. What do you know about cross section, velocity and port/valve area vs. engine displacement and rpm, and what the engine wants or needs? What do you know about any of that regarding hp/tq production? Tell me how much experience you have in induction and engine design and what it takes to make X amount of power for a given combination?
For ideal velocities in the port and valve for a 540 turning 6000 rpm, the areas need to be about 2.64 sq. in. of minimum cross section in the port and about 3.03 sq in. of valve area. The AFR 305 has a min. cross section of 2.99 sq. in and a valve area of about 3.79 sq in. With a 240* @ .05 cam, a 540 turning 6000 rpm needs about 351cfm @ 100% VE. The 305 intake port flows that much somewhere between .550 and .600" lift. I just don't see a restriction but maybe you can point it out to me.
If you want, lets look at 7000rpm. Minimum cross section 3.08 sq. in., valve area 3.54 sq. in. and lets say with a 270* @ .05 cam, needs about 364 cfm. The 305 still has enough cross section (-.09 sq in. is insignificant as far as a restriction), still has enough valve area and still flows plenty of air. Yes, we are talking boats not cars, but I don't think the cylinder heads know that...do they??
And FWIW I would not tell someone to choose a set of 305's over 315's to make 800hp but by the numbers, you can see if you HAD the 305's, it could be done.

YOU said the 315's would be a better choice. Answer the question. If I design a 540 to use 305's and slapped a set of 315's on it, what would happen? Rhetorical question. Answer...nothing.


Answered above. If there was a slight increase from the 315's over the 305's due to being CNC ported and more consistent from cyl to cyl, it wouldn't be enough to justify the cost and not enough power to even notice on an off shore boat. That's the biggest point here. Waste of money, but at the OP's target of 5600 there would be no improvement.

I have no idea what the rest of this nonsense means. You obviously can't answer the simple question of WHY the 315's are a better choice or how the 305's on a 540 are "on the edge ", but you dance very well.
I really don't have any more to say here.

I was told 325's were best for 540....

and thats the correct answer after I cropped all the stuff that no one except a few of us understand.


Nothing would happen if you designed it for 305's and then bolted on 315's? so now you changed your answer from the prior post.



you don't understand the difference in a WOT of 5600 or 7000? If thats the case, something is really wrong with your engine parts choices.

Mine? 30+ years worth of race cars and boat engines. What is yours besides being a former drywaller and now you chose to be a head "expert" Oh yea, I forgot you worked at Dart doing who knows what for a while. So that makes you the expert? I don't think so. I don't post on 20 different forums saying I'm an expert and thinking that the more times I lie and say I'm an expert, that sooner or later people will believe the lie. and I certainly have never said I was an expert on anything. You OTOH seem to have it tatooed to every post. Hey Hey look at me. I'm the best, everyone else is wrong but me. Do you not understand that experts earn that title from OTHER people saying it, not because you think you are the be all end all

And yet, you still haven't answered the question. Typical of you to shift to the personal attack, though. That's when you KNOW the discussion is over.

Youre wasting your breath with this goof. 30 years experience in racing and marine engines, and yet, needed sutphen 30 to build his 600hp 509s ? He cant grasp the concept of jacketed tailpipes, and youre talking cross section widths, port velocities vs duration, etc ?

Maybe he'll answer back with some more "correction factor " lessons.

Ya know, if you had to pay .10 for every google search you did, you would be bankrupt

I missed the personal attack. You and your buddies are experts at that. If you don't like facts posted about you, I'm sorry. You asked about me and I told you. I also posted background about you. The fact that you worked at Dart and did drywall is not a personal attack as far as I can see.

I've answered the questions about the AFR's. Just because they don't agree with your thought process is not my problem.

horsepower1,u and i did not see i to i when you first appeared as horsepower1.i have been sitting back and reading what you post.i told you i am not one to jump on the band wagon and i form my own opinion,well sir you have proven to me that you are for real,and that you post good,factual information.my advice to you would be ,don,t let people like zone suck you into bickering.some people can be shown in black&white but they will still believe what the say to be correct because when someone thinks they know everything they can no longer learn anything.i want to apoligize for posting what you sent me in a pm,i was wrong for doing that and i will never make that mistake again.i have not been posting much lately because i am tired of listening to the bs that has been flying around here lately.

Remember an engine is a compromise. If you are not working on the bottleneck your not going to gain anything. If the heads are not holding you back, putting on better flowing heads is not going to help you. Also don't go on the internet and tell everyone those better flowing heads don't work because you didn't see a gain, you didn't need them. In another application they would work well. From my limited experience - If your going to miss on your combo you want to miss on the small side on heads and cams. It gives you a responsive engine with midrange torque and usually better idle.

Gotta wonder what motor this was done on

no need to wonder,just ask.522 cu in supercharged engine,10 lbs boost,6800 rpm max,heads&cam speced by bob madera,this engine was a total sucess.if this was a n/a build 305 with cnc chaimber would have been used.

I see you dug up some pics of my first boat restoration. Nicely done.

How about you post something you built YOURSELF? Or, maybe just google search some more of other folks info and work and post it as if it was yours. :angry-smiley-038:

Funny that mike t had to post your piston to bore clearance here recently. One would think a guy who spends so much time pontificating about engines here would know what his own stuff measures.:grinser010:

you just don,t know when to quit.i took the block to the shop we use because joe was GRAVEL HAULING as you like to put it.i had the xtra .001 piston to bore clearance added. i have a question for you,is the boat in the picture joe posted your current boat because it sure looks that way.

Great post Mike!

Not for nothing Mike, but I would stick with the guy who sold you those AFR's and his advise before you started listening to others on the internet. The last set of AFR's I bought came from Bob too, and he talked me down to the 305's too. But what do I know, because I didn't build my last boat motor. yes, I had S30 do my 509, because he had the equipment to pull the motor (that I don't have) and worked at a machine shop I trusted that could do everything else that needed done. So my boat was sitting 5 hrs from my house. Truthfully not worth the time to haul it back and forth when it could be done and done well right there.

Anytime you wanna bring that pantera out with the supercat engine, I will gladly show you what I've done.

Mike I hope you don't stop posting because it's you and a few others I look for when I'm looking advice on here.
