Re: pretty dissapointed. (track results)
More timing (somewhere around 38 as long as the fuel is good) will make the engine run harder on top. With that said, you really need to know what cam you have before trying to turn it that tight. When you shift @5500 RPM is that because the motor quits pulling? Have you run a compression check on the motor?
