They will put the sting back in your stinger!

Nice boat

I have seen there stuff as well, eagle cranks and rods, w.dart blocks are very good, IF all the machine work done properly when assembled...thats the million $ question, I had my 482 apart 3 times getting the clearances right...Rob

While I am not a proffessional engine builder, my .02 says that Eagle parts are on the lower end of available internals. They are prices cheaper for a reason. I understand they are heavy and are of a lower grade steel. If your intensions are to build an engine to beat the hell out of, I would recommend a Callies crank , Lunati ProMod rods. Dart blocks are top of the line, no troubles there.

What is the most HP has any one gotten by boreing out their 5oo EFI's and having their ECM's reprogramed.

Vinny,
Are you building a supercharged 565? Are you going to put that in the Convincor?

Rob,

No I am not. If you are refferring to the question and answer posted in this months HotBoat... I never sent in that question. I did post it here on OSO. The thread was highjacked over to HotBoat Magazine.

I was kicking the idea of a Whippled 565, but decided not to. I am building an NA 565 for a spare.

I have a 572 NA that they built 730hp and no problems as of yet after 10 hours. The only issue I had was their wait time was quoted at 6 weeks I ended up waiting almost 10 weeks. That was ok because it gave me time to get the rigging cleaned up.

I would focus on the engine builder, not the parts. Let the pros pick the best value in parts. Invest an extra $3000-5000 get the absolute best builder/engine rigger.
