I am looking to get the most out of my 71' 340. I love driving the car. It is a stock bottom end, J heads, Air gap intake, Comp XE 274 H Extreme energy cam, holley 650, 4 speed and 3:55 SG. Oh and it has a new 2 1/2 exhaust on it. I just love driving the car and it really gets busy when it needs...
