68 327-had engine trouble for awhile now. sometimes runs great sometimes stumbles under load. just started having exhaust backfire and think its related. did a tune up points,cap,rotor,etc didnt fix the problem. just put new world heads on 6 months ago so i hope it isnt a head problem. the header on the backfire side was sort of loose when i checked it recently so i have a feeling. could it be the distributor? its pretty old (original). definately not the carb (some problem with different carbs). note, 2400 stall speed installed around the same time as the problems started.

yes, ive changed about everything thats cheap in the effort-cap, rotor, points-dwell at 32, wires, plugs, fuel filter, fuel pump, retorqued the intake, checked the vacuum lines for cracks and the timing checks out.

i will double check the order however the tune up was done several months ago and the car has ran good on occasions since then (but for the recent exhaust backfire which is continual during idle and accelleration).
