SBC 406, JE dome pistons, eagle H-beam 6.0in rods. Dart heads. Scat crank, full roller 650lift cam. Makes about 650hp wondering if I should spray it or not. 12to1 compression, not sure about somplete specs on cam. Would spraying a 100-150 shot be taking a gamble or not?

 

Its always a gamble. But the odds are in your favor with a good tune. Should be no problem if done right. Dont be afraid to Look around on here and ask questions. Lots of knowledge you can get on how to make it happen.

 

Race gas and a good tune up and you should be alright.

 

Sweet, 110 is what ill be running in it and a good tune on the carb im assuming since it doesnt have a pcm.

 

You need to be sure you have everything tuned in perfect on motor before spraying nitrous, carb tuned in, correct spark plugs for nitrous, correct amount of timing being pulled, etc. I'd start with a small shot just to test that everything is working good, check plugs and progress from there.
