you'll never have to much compression on a nitrous fed motor, i wanted to go 14:1 but decided against it, kinda wish i would have since i dont drive the truck much anymore, then again it depends how often he plans on driving the truck or is strictly race, i guess the main question his how much he wants to spend on heads and how fast does he wanna take his setup


by the way 317s ar junk on a nitrous fed motor
