Right now I am going from a 305 to 350. The builder on the engine is a pro drag racer. He is also installing and throwing in 350 turbo. 1) he said tail on trans not long enough. Anyone have this problem. 2) getting rid of computer. Was told to do this from guy who does state inspection on my car. Also told me to find trash can for smog stuff. Anyone do this. 3)having problem with speed cable vs speed sensor. How did people solve this.
