the biggest signiture!!! ^
call up Nate Mccoy, or Brandon over at wildcard, get your cylinders ported correctly! scrap the fattys and get some pipes that will pull a higher RPM(CPI, SHEARER). get some new carbs 33-35mm. change your timing from +4 to +7 and change your front sprocket back to stock.
if you really want to beat that 450, throw in an override tranny...
