The Stovebolt Site Forums The Shop Area Engine Shop Valve Adjustment Question (Chevrolet 235ci)

Many thanks Tim, so my engine I believe was a Dealer Rebuild out of California, as the Serial Number is polished away and it is re-stamped with a: "DR 155429 CAL"
The casting number on the engine block is: 3764476
The casting number on the head is: 3836848
