Indmar charges 13k for this motor with the harness which is not a bad deal as it would work great for a project like yours

So is that with cast or forged internals?

I think they are used in Mastercraft ski/wakeboard boats. I would like to know how the torque would differ in a performance boat. Additionally, what is changed to go from wakeboard to performance?

In 3 to 6 months as far as major OEM marine engines Mercruiser / Mercury Racing & Ilmor will be the only one's left offering Big Blocks everyone else either has all LS motors or at least one LS motor to replace their big block offering.
The weight as I was told by Indmar was 467 lbs for the base like the pic in the GM performance website as I called it a full long block - the block, intake manifold and heads are aluminum. |

Mastercraft has used ILMOR engines exclusively for about a year now. Ilmor offers a non-supercharged 522 horsepower engine with far better internals:

Boatlesss, can you get me the contact info or a link to the $13000 LSA? Thanks.

If I recall correctly I think the reason for the cast pistons was all the complaints on the auto side about the piston slap being forged aluminun years ago. After the motor was fully warmed up and the piston expanded from the heat the slap went away on most of them but not all. A cold motor the piston slap was pretty darn loud. Again I think the cast piston took care of the slap but not 100% 4 sure.
