1972 340 testing by Nick



This was a pretty good episode. Nick took a stock 1972 340 and did a mild build on it. Stock was 8.5:1 compression and now it has 9.8:1. Some mild porting of the stock heads and intake valves are now 2.02 vs the stock 1.88. Stock cast iron intake, stock thermoquad carburetor.

Unfortunately the owner didn’t give Nick the specs on the flat tappet cam.

Hooker Super Competition headers made only 16 horsepower 22 lb feet of torque over the restrictive 72 manifolds.
