Does an original 1976 chevy c-20 van with 350 4-barrel have 2 or 4 bolt main bearings
The only way I know to tell is to pull the oil pan off, you might find a buddy with a borescope to stick in the oil drain hole, no way i know of from the outside appearance
I believe an original 1976 Chevy C-20 van with 350 4 barrel has 4 bolt main bearings. The bolts attach the main bearing to the block of the internal combustion engine. For more details, you can check with a mechanic.
