nitrous on a big block

[sam 74]

i'd stick with 125 or less, i've run nitrous for years without any problems, you'll want to pull between 2 and 4 degress out of your total timming depending on what shot you run. i've run with a seperate cell for race gas and i've run directly from my main tank, the key is keeping your fuel pressure right while the solinoid is open. you may want to back your plugs off i step colder with a 125 shot.
