Just pulled the motor out the 82 and need help

[Rollinsqrbdy]

Well Thanks to everyone, Everyone was so helpful. After getting all my cast numbers and doing some research I know know my motor(3970010) is a 350 four bolt main. Assembled in Feb. 27,1976 in the Flint plant in Detroit, Michigan. I also know my crankcase cast# 3932442 and know its stroke, years made, main/rod Journal size, and know it has cast large Journals. My Head casting # is 333882 which was made from 70-82, the valve size, H.P levels for head, and chamber size. The motor was used in Truck, chevelle, nova, and camaro's. Theirs also three different motor sizes which has the same block number 3970010. The 302,327, and 350. Thanks again to everyone who helped. I went from " Yup The motors got oil, to all this great and useful info".
