    how much nitrous will a stock magnum motor take

    Most were hyp. if not cast. What really takes a beating are the rod caps & bolts, especially if the pistons are heavy. I pulled apart a factory 440 that had a stock bottom end, it had several 175 shot passes on it, when i tore it done, the caps slipped right off the rods. Not saying the...

    how much nitrous will a stock magnum motor take

    Nah, make it 300 & add 20* lol. Ok, seriously, I'd start with a 100 shot & pull about 4*, If you run a dedicated fuel cell up front with an elec. pump strictly for the plate, I'm sure you can get away with 150, but i wouldn't go passed that, run 110 in the cell & premium in the tank for the...

    Thanks, so was i, I got hooked about that same age with mopars, my 1st. mopar was a 70 Sport Satty with a 383 super commando, had all the options, even power windows, it was B5 blue, but it was rough, needed full resto but ran like a champ, only had 87000 miles on it. Its just time for a change...

    Hp/tq estimate on 5.9 magnum?

    I would agree, right around 325ish at the flywheel, I'd think 335ish with a good tune.

    comp 280 magnum or mp 280 cams can't decide!

    The comp 280 has a dur. of 230/230 @50 & its on a 110 LSA & 106 ICL, The MP 284/484 has a dur. of 238/238 @50 & is on a 108 LSA if i remember currectly, I'm thinking the ICL is 104. I think the cam Duster360 listed might work good.

    Done with Magnum Swap!

    Thanks, I was really surprised how well it responded to nitrous, did you check out the video in my sig., i ran up against a factory 69 Yenko 427 Camaro 4sp., i wasn't on the bottle in that pass, he ran a 12.4 to my 12.5, we were neck & neck.

    It should, i'd go for the 360 magnum & just carb it. You'll need to run an electric fuel pump, so its best to either sump the stock tank or run a cell, You could fuss with all the EFI wiring but i wouldn't.

    I'd say the car will run in the 11s at sea level no problem. Looks good.
