Before you start making charges to your engine,do you know what rpm you are already spinning before you go wide open to bring it out of the turn? You may be making lots more power,but just throwing it away on wheelspin. Are your tire temps still about the same,especially the right rear?Have you rejetted the carb to go with the cam and head work? You've got a lot more homework to do to dial that engine setup to your track. Hank
