I have a 69 351w. I would to have about 10-12 pounds of boost on it and occasionally spray it with some n20. What kind of compression ratio should I go with? I will probably have fully forged internals too.
That kind of boost I would imagine on pump gas your looking at 8 or 8.5:1, had a little ricer machine that ran 12lbs with a 35 shot. motor lasted 2 years before rods went bad. Had 9.5:1 That little machine was beat ontho.
