Upgrading my 340
3 pedals....... Put an automatic in it and you will go faster..... Unless you have an expensive clutch to get it away from the Starting line.... Something else is Chassis Dyno results can be skewed due to no Converter Slippage meaning you may see a bigger number than what you will with an automatic. A close friend of mine who has now passed ran a dyno at a well known carburetor entity and that was his findings running cars.......
However 3 pedals is a blast. What is the Low Gear ratio of the Transmission? 60ft,330, and 660 et and mph if you have that info.....
