Read this thread back4more addresses automotive crate engines understandebly for the non-mechanic compared to marine engines.

More clearance in the rod bearings for oil flow to remove heat from the bearings. Re balancing the rotating assy...If its anything like the ZZ502 it will rattle it's self to death in no time.
If your looking for a 1000hp blower motor you better plunk down the cash for top of the line internals...not to mention a beefy aftermarket block...There is no such thing as a cheap marine blower motor making 700+hp.
I not slamming this bad assed crate motor, but it is not for powerboats...I read alot about people blowing up the 502s running them at the track.
I know nothing about detailed marine engine building but learned a bit while having mine built.

Oh, and we did'nt even talk cams and valve train yet....

As well as everybody else! They have monumental buying power and what do they do? Boost prices and have huge profit margins. I can't believe the FTC didn't see them moving in to squash the competition and kept approving one merger after the next. They put Vovo-Penta and OMC all but out of business.
I did my homework real well and these guys are making more on a boat than the manufacture and that's only if THEY don't already own the company.

Also, I figured the crate motor would not be an application for marine use probably but just look at what under 20k will buy you. We should have decent 600 HP motors for 20k by a major marine builder who "own's" the entire fleet. The only boat company they won't own is the US Navy and I'll bet they supply to millitary as well anyways.
