no cause to use that compression you will need an agressive cam and that will cause your powerband to be from say 7k to 10k or so. also to run a all motor header to use that powerband you are still goin to have to hack up the core support. good luck dude but I wouldn't go over 12:1 on nothing less than 93 octane and very conservative timing and fuel tune. on race gas setup a more aggressive tune but don't expect to make more than 210whp or so on pump gas and that is tops. that should be good for high to mid 12's if you are keeping this car streetable. most of the fast street cars are actually trailored all the time. to hit 11's to have to strip it to nothing and plan on a trailor.
