Here is my problem. I am getting the car ready for tomorrows race. I done a compleat tune up, accell super coil cap and rotor, ac plugs, plug wires, fuel filter, rebuild the carb with .104 and .110 jets, high flow needle and seats, changed the oil, cut the hood out under my new 4" cowl.

I am getting a extreamly bad miss at about 4 grand and up. It has all the tq. on the bottom end and winds up good but around there it starts missing. I checks for burnt wires and they are ok. I have played with the timingeveryway possible and no luck. I am stumped. I am wondering if a module would do this. Its a stock vac. advance dist. It even sounds rough at idle. I tried a second set of plugs and wires to no use.

Someone please help me. I am lost.

Thanks
