Get an RV-type camshaft,a set of headers,and upgrade the rest of your 302's exhaust system.You might even try to have the stock heads mildly ported.This should help your 302 become a stump-puller for under $2,000.Good luck.

You can't port the heads or put a cam in it unless you convert it to mass air. Of course you can do it but it won't gain any hp..
best thing for a 302 for pulling is gears. The next thing I would do is exhaust!

I agree with adding lower gears,but you don't necessarily need to switch to mass air(vs. speed density electronics) if you choose a mild RV-type camshaft that is "computer-compatible." Many aftermarket cam companies offer EFI302 cams that work well with speed density systems.My EFI302 Bronco has an aftermarket cam in it,and it did add horsepower&torque to it.Keeping the lobe separation between 113-115 degrees&shouldn't be a problem.For an all-out horsepower EFI302 truck engine,I'd add mass air,but for stump-pulling duties you'll need torque more than horsepower.A mass air conversion kit would push the upgrades in excess of that $2,000 figure.All said,exhaust &gearing upgrades are probably the first step to take.
