[QUOTE="yacob.naif, post: 1637603, member: 565696"] Bump it UP to 8.5:1?????? That's WAY low for a NA car, and depending on the year of the 350, it could've been designed to run on leaded gas, which had octane ratings closer to 100 than our 87-93... Most of which probably ran close to 12.5-13:1 compression. What's your main objective by switching to fuel injection? Sounds to me like all of the modifications you're doing are all naturally aspirated, and would benefit from the fueling tweakability of a good carb setup, not to mention there's so many edelbrock carb manifolds for oldschool 350's that add a good deal of horsepower by themselves, and you'd be able to find one that makes peak power in the same powerband as the cam you go with. What kind of power are you going for? You building a torque-beast, or a high-end horsepower track car? [/QUOTE]
