Hey guys looking to put together a mopar combo to run ultra/ultimate. I think my best bet would be a 540 b1 combo on nitrous. It looks like the car would have to weigh 3250. Is there any way someone could give be an idea of the horse power neaded to be competetive in this class and run 4.90 to 5.0 in the 8th mile? A all out na b1 motor can make 1100+ so I figure if it's built for a big single stage of nos if I can make 850-900 on motor than hit it with a big single stage plate kit that would put me in the ballpark to not just be a class filler but actually be able to be competetive. Anyone out there that can give some info or tips would be much appreciated thanks in advance. Combo would be going in my 67 barracuda notch back.
