Help with specs on 97 vortec crate engine - Third Generation F-Body Message Boards

farm-kid/88camaro · 01-14-2001, 09:01 PM

I just recently purchased a 97 vortec crate engine. I checked the head castings and verified that they are the L31 vortec heads. The block is casting 10243880 which indicates a gen 1 crate motor with roller cam and one piece seal. It also includes the damper and oil pan.
Im not sure if it is 4 bolt mains, how would I go about checking?

Does anyone know any specs on this engine or where i could find some? Im wondering if it isnt the 300 hp H.O version which is now the 330 hp H.O.

Any help would be greatly appreciated
thanks, jon

Turn the engine over, pull the oil pan, and look and see if its 4-bolt mains. But its probably 2.
