View Full Version : My 454 has...what?
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.

Scott, where would I find the block casting #?
There is the following information located on the port side of the engine kind of near the bellhousing:

Type: LB 74L EFI
Ser. No: 0000004601

I have never seen a 454 with 2 bolt mains.

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
