Thinking of building a nitrous 318 to run a limited heads up class at my local track. If I stay below 335 cu in. I can still run a single plane intake and a single plate system with up to a 65 pill. I think I'm restricted to iron heads too so I can get a weight break. All that being said, do you think it is possible to build a 318 or maybe an offset ground crank in a 318 or 273 block with n20 to run mid 6's in the eight in a 2900# car? I'd be running a glide and an 8 3/4 and the car still has to be leaf sprung with a 26x10 tire. It's a tall order but so far I haven't seen any Mopars in the class
