Saturday is out for me, the wife is working and I have my 9 year old.
Bring the 9 year old Sunday is ok if you get there early.
He says the motor is a 2 bolt main 350 with large journals. (He mentioned original motors for that year had smaller journals. Is this true ?)
The 350 never had small journals. The original 350 was rated at 295hp. The casting numbers on the heads will be under the valve covers. The block code should be stamped on the passenger side in front of the head. The casting numbers for the block are on the top back side of the block.
