In my 1996 22' classic is a 7.4 Gsi Volvo package.

Does this engine have;
2 bolt mains, cast crank/pistons, and oval port cylinder heads, or,
4 bolt mains, steel crank/pistons, and rectangular port heads?

Would this info be on any serial numbers, and would anybody be able to interpret the numbers? Thanks!

Parts list shows 10 outer & 10 inner main bolts IE: 4 bolt block!

Was not sure though any of the higher perf's that I got into had 4 bolt bottoms.

Prod. No: 3856688
Type: LB 74L EFI
Ser. No: 0000004601

Tony, your Gsi engine is the same as a Mercruiser 385hp 454 Mag. It has a 4 bolt main and forged internals! Only difference is the accessories added to the engine and you have a better drive! :D
