It looks like Crane is not the valve train component for me!

Soild rollers are a PITA always need tear down and inspection. Usally due to high spring loads bearings in lifters and rockers often fail. Have pulled rockes of such engines and find needle bearings fall out or have already. Pure race might go for it but not for pleasure / poker runs/ racing combo.

[ATTACH=CONFIG]532279[/ATTACH][ATTACH=CONFIG]532280[/ATTACH]well the dyno doesn't lie, 603 hp. Paid for 650, Builder Said it was still building power when red line was reached but with a stated rpm limit on the ( sales brochure ) and proof of the dyno sheet that stated hp was not attained sounds like misrepresentation to me.

Good luck with that. I am sure the original builder would argue variations in different dynos being the reason for the less than 10% variation. It sucks, but probably nothing you will get out of it. How about advancing the cam a bit to try and bring your peak HP down under redline?

[ATTACH=CONFIG]530314[/ATTACH][ATTACH=CONFIG]530315[/ATTACH]Mcprodesign, these are not merc engines. Sorry for any confusion. These engines are Bullet Engines 650hp normally aspirated series 540 cid. They are Merlin III blocks, this one has a Callies compstar crank, Manley H beam rods, Manley flat top pistons, Edelbrock marine rpm heads, Crane cam, & lifters, Crower pushrods, & Scorpion rocker arms. At least that is what the part #s are telling me.
As an FYI: Eddy heads used on many 500-600hp NA Builds. You don't really see'm on NA builds higher than that.
AFR's / Specialized Brodix and etc, yes.
Many 600-640HP 502's out there with AFR's.
Many 600-700HP 540's with AFR's.

I just got my computer to bring up the dyno sheet.
There is some problems !
Mid .300's for BSFC's ?
Don't think so. This usually means the dyno sheet is jacked up power wise.
I'll run some #'s when I get back in from blowing leaves.
And yeh, the fuel usage and air flow used is down from strong motors in the mid 600's.
The dyno operator should have pulled the engine to higher rpm so the owner can see the whole picture.

I just wanted to post the dyno results that we got so anyone can see what I have. He said it wasn't done making power at that red line but this isn't a race boat and was not propped to run above the stated rpm. We are changing heads & stuff so I will update when we get some progress made.
