Tried something different... Just finished installing the Holley 500 2 brl on a mainly stock 302. Feels like a 10-15 hp difference. No manifold change needed. A definite improvement and mpg still at 18-20 running 68 main jets.

Sounds good, a stock 302 probly couldn't take much more than that under normal circumstances anywhoo.

The Carb was $200.00 on E-bay, rebuilt & Guaranteed to bolt on and go. Outta the box it ran good, but i suggest swapping the 76 jets down to 68-71 depending on outside temp. This time of year in Mass. the 68's work perfect - plugs are golden brown and no spit-up coming out of the exhaust. The throttle response is immediate and makes the 302 feel like a bigger engine. I would recommend it if your motorcraft or autolite carb is getting tiredand you want to stay 2 barrel. I set the idle with a vac. guage, and am at 19 in. vac. So far mpg is still the same unless you put your foot into it, which is often.

Not too bad I guess, specially if it runs without a lot of tinkering.

You ever see Currie's(Currie rear ends) 65 Mustang he built for Panamerica racing, which is on the worst roads in Mexico. Rules are quite clear & you have to run a 2 barrel, at least that's what he's running, i think its the rulebook. Anyway, the little 289 puts out 450 plus HP & says the throttle response is just awesome with a 500cfm 2-barrel. He did mention getting a few mpg less than with a 4 barrel tho, i guess at WOT that 2 barrel is movin the fuel!
