yea i will use nos but not all the time ( only at the track) coz 65% of my time at the track and i dont have a tranny yet and the rear end is a 9" with 4.11 ratio. the PRM range about 2500 -6800 RPM Hyd. Roller and 11 to 1 if i can .
what im looking for is a powerful engine that makes more than 650 horses without NOS and if the tall deck is the way to go i dont mind, i can get a 572ci from World Products coz im thinking of getting one of their blocks or anywhere else . So what u think?
