Today, dollar for dollar, is the 318 faster than the 340 ???

A 71 beefed up teen against a 73 stock 340? Sure. The teen comes out on top every time. The 72-73 340's ran good but not impressive compared to the earlier 340's.

plus the 73 is what we called a smog motor. All the 71 had was a PVC valve
