302 tuning question.
My freshly rebuilt 302 started driving like crap last week, and I finally got around to seeing what happened. It was running like it had a vaccum leak, but it was still pulling 18in. I pulled the plugs, and they were all carbon fouled, this occured with about 200 miles on the engine.
So, what should I do next? Engine is a stock 302 bored .030, mild cam, Windsor Jr. cast heads, Edlebrock intake, Holley 4150, stock exhaust, Pertronix ignition, stock coil.
I currently have the timing set around 16 deg., and went one step hotter with the plugs. Parts store was closed for the day, and I couldn't do anything else.
I think that my problem may be two-fold, weak ignition and carbs jetted too high. I checked the resistance on the wires I have now, and measured between 7K-9K ohms, depending on the lenght of the wire. According to Holley's site, my carb has 64s in it right now.
Since I don't want to spend the dough right now on upgrading my ignntion system if I don't have to (my boiler went out Saturday night, and I had to spend 3K on a new one), what's the cheapest hing I can do if I end up fouling the plugs again? The carb was set with a tach and vaccum gauge, and seemed to perform fine, until the plugs fouled out.
If I do have to do something to the ignition, what's safe? I know the Pertronix ignition can only be used with points style coils, but would that be enough to do anything? I'd like to avoid moving to an electronic ignition system for the present time if at all possible, just don't have the cash right now.
