New engine build up
How far can i build an engine and still run it on 89/91 (low/medium) grade gas in a 302? I already have a Edelbrock Man/Carb and i plan on a cam and headers too, but i was wondering if i took out the emissions how far i could but up a new block to replace the tired old 79 engine.

Keep the compression to around 9-9.5 to 1. Watch the cam overlap, too much and you're bleeding off compression and lose bottom end. Too little overlap with too much compression and you've got an engine that like higher octane gas. Timing has a lot to do with it too. There are no hard/fast rules to how far you can build it up to. The combination of parts and timing, will determine what octane you can run. Want a livelier engine than your 79? Get a 5.0 out of a 94-97 F or E150, swap the intake for yours, add a set of 1.7 "Cobra"/Crane pedestal rockers add the headers and you'll have a nice rev happy, torquey 5.0 that'lll pull from idle to 6000 rpms. Leave the stock F4TE cam in it, that's the part that makes the most difference here, that and the better E7TE heads. And it'll be happy with 87-89 octane gas and the max amount of ignition timing.
