I just got my rebuilt engine back in my bucket. It is an 1986 Chevrolet 350 with a new stock pan and the dipstick that came in the old '86 350. I'm getting ready to light it up so I obviously needed to put some oil in it. I put most of a quart in the filter and the remainder of that quart and four more quarts (from a gallon container) in the engine. That was last night. This morning I checked the oil and it is at the add oil mark on the dipstick. As best I can tell there were no 6 quart engines in 1986. So I'm asking . . . has anyone else experienced anything like this before because I'm completely baffled. I certainly don't want to overfill the engine with oil and I have no clue.
