I started off with a GT 750 on a 230 frame. It was actually used to pull a sled and I turned around and changed the gears around just to see how fast it would go. I figured out that it was to much motor for the little frame. Then I decided to put it in a LT 500 frame. It has taken me a year to do this all and now I have it together and running. So, far I have found out that it is a much better ride. I am hoping that I and get out to the sand drags to see what it is really going to do. This here is a 1987 Quadzilla chassis with a 1972 GT 750 motor and made my own custom pipes. I have tried this setup out and working on rebuilding a 1974 motor. I have seen on here that they have talked about the rocket and I am wanting to try something that or any other ideas.
