340 Build Spec's

The 71 TQ was a solid fuel carb. 72-73 was a better unit. 71 manifold is good. Scamp be careful on the compression if you want to run low or middle fuel. Short cam won't allow much. 1 5/8 tubes loose 7 % on 340/360's. I learned this from a Hedman engineer many years ago. TTI steps will work, but expensive. Bowl porting is easy and cheap if you do this yourself and there is no penalty. Clean up the bowls and blend into the bottom cut. Low lift flow is better and more flow everywhere in the flow curve. Also back cutting the valves is inexpensive and pays off big in low lift flow. Good lick. Terry.
