I plan to take this engine out of my truck and put it into a 1972 ford gran torino sport (3500LB). I want to stay with pump gas but dont mind haveing an aux tank with the good stuf when i run nitrous. Also I have an Automatic trans.
Dose anyone with a 400 have experience useing nitrous with this motor? I think I will change to a roller cam, mill my heads down so I get 10 or 11:1 comp (would like to switch to aussie heads but I have thousands in mine already), switch to a wiend single plane manifold, and drop in forged pistons. With forged pistons how large of a shot of nitrous can i safely use with the stock crank, rods, and 2 bolt mains? I would really like to use a 250 to 400 shot of nitrous. I plan to use a two stage plate system like Cheater two stage or Pro two stage. Or would i be better off useing a fogger sytem. Perhaps a small forger system backed up buy like a powershot plate system. Kind of my own two stage set up. I would call Nos but they probly dont know 400's that well, do any of you guys know a cleaveland guy at nos? Well anyway I would like to run high nines or low tens with this 3500lb torino. (I know you guys are truck guys but you know your stuff) One more thing, anyone know any good gides to building proformance c-4 tranys. I would like to use a c-6 but the car has a c-4 and its to much hassle to change.

Buy the way, old Ford trucks rule.
Mines a 78 ranger 2 weel drive and it dose better in mud than my buddys 84 chevy 4X4. Gess its becous of that 4000lb steel flatbed on the back.
