Ive got a marine 454 from a 95 Four Winns Horizon 240 sitting & waiting to take its place of my 350. Unfortunately before I do anything more Id like to see if anyone knows anything about the engine I have.

The engine is an OMC 7.4L 330hp with the MPI intake, made in 1995. I have tried google and random boat forums but havent found ANY sort of specific info on this engine. Id like to find out about its compression ratio, the systems/sensors used and such.

Also, if anyone knows, what sort of conversion is necessary for a marine -> car application. Thank you.
