although i put a car into the 12's with stock TB and stock intake with a b-cam and elderbrock heads, i would recremend putting a 65mm TB on cuz your combo likes to pull up top..one easy way to see if you need a TB is run your car at WOT and read ur vacuum gauge at about 5000-6000 and if it reads any vacuum then a TB will help...
i run a 70mm TB on my car but my cam really needs it and i have no lack of tourque cuz of gears and the fact that the cam pulls from 1000 to 6000
