Did you give the lifter enough time to bleed down first time around? Sometimes it can take a minute.
Hyd lifters on solid cams is done all the time. They're called hybrids.

Everyone who works at Bullet cams are morons.

Coming from a guy who has made a living burning his engines in his boat down , losing control of it, flipped over, crashes into rocks, tells people to moubt their intercooler pickup behind the step in the hull, and jumps down anyones neck who questions his "cam guy" ...

Its ok for him to blast bullet cams , but not ok for anyone to talk about his cam guy. We need more guys like him in the offshore community.

$6000 engine oil pan, and what outdrive on the 26ft donzi ?

Weeks of piddling with it I was done. Called every cam company in the United States some you've never even heard of and everyone told me you can't run a hydraulic lifter on a solid cam unless you have lash at the valve. Based on my findings I would tend to agree with them. To my knowledge this is why Comp and Morel came out with the HLT lifters. With only .005 plunger travel you could lash the valve and run a solid cam. These setups were directed towards Class racing that had rules where a Hydraulic lifter had to be used.

1. I didn't say everyone was a moron.
2. Everyone (well maybe 5 out of 10) people that boat on the river I do hit the rock pile.
3. Never burnt an engine (have blown up a few) but that's what happens when you put everything on tilt
4. Never lost control
5. Never flipped
6. Many manufactures mount behind the step (Outer limits was 21' forward of the transom behind the step)
7. $1000 oil Pan
8. I was thinking Aplha unless you in your endless knowledge had a better idea.

All this cause Joe is still butt hurt that Eddie didn't take Joes suggestion of using a 305 head on his 525. Now Joe is going to use social media and all means necessary to put Bob out of business. And how did we go from Engine Developer to Cam Designer? Which is it?

Oh yes, ealeash. I remember that. That was right before your obsession with bob, and you had told me all about ealeash, and his incapable boat driving skills. And bob telling me what a hack job his wngine builder was going to do, by attempting to modify the port openings on the 265 afrs to match his intake.

You bashing ealeash,, bob bashing ealeash, and his / your engine builder. Was it cms that was building ealeashes engine ?

Lol, your whole crew is a farce, and yet you guys go around bum wrapping people like bullet cams, bob teague, etc. Keep trying those drag race engines in your donzi, that program works well for you. Believe it or not, there are some guys who can put together twin 800,900,1000+ hp engine combos, and go boating very weeekend with the wife and kids.

It very well could have. It was a Bullet/ Morris Cam. I didn't install or degree the cam. By the time I got to it motor was in the boat. I thought initially the cam was installed wrong. So I used the degrees on the balancer and a dial indicator on the pushrods to make sure it was installed correctly everything checked out fine (my initial thought was that it was installed teeth off on the timing gear). Using the method above I determined it was installed properly. Don't know that I could have checked run out that way and didn't even think to at the time. Had another cam overnighted put installed it next evening after work and went boating. I still have that cam laying around somewhere...

Ask ealeash eddie how i knew about the proposed hack job on his intake ports , and how thats why, it prob wasnt gonna make the power of the other build with the 305s. Sales pitches galore, and bashing own customers....you guys wanna keep playing the innocent , mild thunder is a bad guy game ?

I didn't get any of that information from Bob. Actually I was the one that told Bob what was going on with that whole ordeal. So if that makes me the bad guy. So be it. I'm bad.

Exactly. And thats how it got to me. Thank you for pretty much proving, what many said on that thread that was deleted. Nothing but bad wrapping other people, bashing other builders, and behind the scenes gossip. And then you all here 1 version of the stories, and act like you got the gospel version .

If you go back and re-read the PM you will see where I got that information. I was at work (working possibly) and got 2 phone calls from two different people out of the blue... If I remember correctly you an Eddie were having a back and forth because of the cylinder head suggested. I sent you the PM to try and calm things down and basically say hey the guy is an idiot (sorry Eddie) and Leave it be kind of thing.

Only if strippers are provided. They must be under thirty, 120lbs and have all there teeth as well. I'll have some more stipulations in a minute.

Griff 10-13-2015 12:18 PM

How about you guys stay focused on the 540 cam discussion????

Stripper talk is fine too:lolhit:

You may not believe this, but I would be into that...one problem, I don't drink....but I'm sure coffee is easy enough.

Mrs icdedppl makes great lattes after a day of wrenching on boats . We should opt for decaf at this event however

I don't drink either. That's why I suggested strippers. And we could all discuss the 540 cam

Can you leave 'no teeth' as an option ?

hammerdown500 10-13-2015 07:35 PM

go with your proposed build you will be happy with it for what u r looking for. I have built a 540 and 548, with the same basic setup and now I have a 509 doing the same. all making basically same hp(575-620). actually have been running a 489 with the 741 cam in it 10.5:1 comp and running well for 2 seasons. making 550hp.

beer!

You might consider talking to ATECO , ask for bill. 847-623-2737. Built a pair of 540 short decks, out of HP500s , ran great , with good manners. And great torque. Very reliable . Spend the extra money on the dyno time. It is worth it. Drop them in and they run.

Are you running the 335 heads ?? I am lookin for specific feed back on if they are perhaps a bit large. Also what are you running for an intake?

That's all going to depend on the rpm of the motor. You really need to do a velocity profile on the motor and see how much air speed the motor will need for the max rpm then you can select the proper head. My guess if you want to spin 6000 with a 540 you will probably end up between the 315 & 335 head. Most will say in that case use the smaller head. Being as you already have the 335's I would put them on and roll with it.

Careful. Before you know it you will be blowing up stuff running your boat into rocks and flipping it over.

After more reading and a couple of questions asked I have found the 114 degree lobe seperation version of the 741 cam is crane part #139671 . This is the stock 525EFI cam I believe but at a more reasonable price than from the Merc.parts shelf.

I have a 540 with AFR 315 heads that had a crane 139021 witch is pretty close to the one your looking at (112 lc). It was pretty much done about 5400 rpm.

ICDEDPPL 11-14-2015 08:07 AM

Put in your info, get a custom cam based on your set up for cheaper than Crane. Easy

Really hoping that this will pull to at least 5800. Is your cam setup straight up or retarded/advanced ?

fbc25el 11-14-2015 12:05 PM

Straight up. Pulled it out and went with more lift 660-650 more dur 246-250 @ .050. I can tell you a 741 in a 540 will not pull to 5800.

To be clear I am actually looking at 139671 which is the same profile as 741 but on 114 degree centers. Also I am using 335 heads. What are you running for an intake ??
