It could be.
Research tells me the following: 7/16 Main Caps (2 Bolt): 70ft-lbs 7/16 Inners (4Bolt): 70ft-lbs 7/16 Outers (4Bolt): 65ft-lbs 3/8 Outer Main (4Bolt): 40ft-lbs
4bolt 350ci
Probably 4 bolt.
if it has the double hump heads..more than likely 350hp. If not 250hp

you need a casting number some have thicker walls 2bolt vrs 4bolt mains ect.
Around 375
All 305 Chevy small blocks made from 1976 to 1996 are 2 bolt main bearing. You will not find a 4 bolt 305 that was made by the factory. One may exist, but it was not made by GM.
no you cant. but i will go a bit deeper. im guessing you have the 350 with code ending in 0010 (its the most common)...i have had three of the 0010 350 blocks.... one was a two bolt and the other two were 4 bolt mains.
I've rebuilt many 1992 through 1995 350 engines in Z71 and siliverados and have yet to see a 4 bolt main. I've only seen them in the 3/4 tons and heaver.
