I have a 1974 duster with 3.91 gear 8 3/4 sure grip rear end, 727 trans built with a 3500 stall converter. The engine is a 2000 360 magnum stock bottom and EQ cylinder head with 2.02 intake valves, headers and mild roller cam. 9:1 compression ratio , Edelbrock RPM airgap intake manifold and a 750 Holley carburetor., MSD ignition system. The car runs 12.80s, what do you guys think about 100 shot nitrous system on this combination? And what be the safe max before catastrophic failure occurs? My goal is 11.60s quarter mile. your input will be great.
