Where can I find the casting numbers on a 1972 Truck?
You can either look up the casting numbers (under the valve covers – then www.mortec.com ), or pull the intake manifold and look at the shape of the intake ports.

Is the 1972 402bbc worth the money?
Yes, it is worth the money. My dad had a 402bbc with 9:1 compression and stock casting heads ported and had 600fwhp naturally aspirated. It was built to run a 300 shot but only shot a 150 on it. Had it in a 76 silverado, thing was insane!!! 2 bbl? The big block should have gotten a 4 bbl. Heads are the big thing.
