depends, do you have forged internals or not? You could do it with the forged internals and youd need to re-evaluate your piston ring end gaps since your putting alot of pressure on your engine.... hmm you might want to have a mod move this post to the power adders section where they might know more about it.... i see your in sacramento so im assuming you go to sac raceway...hope to see you there...oh and what are your times?
