Thanks guys. I was wondering about the speed/acceleration issue because right now I have a 15 tooth clutch bell and 47 tooth spur on the truck and seems like I'm not even getting over 30 mph and the 14/44 second gear looks like it won't go much faster than my current setup. Will I get the same results speed wise as cenracer, with the stock engine, or will my speed results be slightly lower than his?
