i have replaced ignition coil, 2 fuel pumps, 2 carbs, two condensors, wires, plugs, and still no solution. car drives fine on start up, but once i drive it for 10 to 15 minutes the idle drops and the car will backfire if i try to accelerate normally. it just recently started so no its not the fuel lines too close to the engine. plus i put a special coating around the lines to kleep them cool. wat could it be? will the points cause this, will timing being off cause this and why only after a 10 minute drive? anyone with the answer and an explanation of why their answer would or might be right will get best answer.

i removed the intake and no..not aluminum. its was cast iron i believe. it was very very heavy for a manifold. i remember thinking that when i replaced lifters and pushrods. i dont think the gasket is bad. also i noticed when it dies on me and i try cranking it white smoke comes out

Are you getting your parts at a store like Auto Zone? If so that could be some of your problem right there. Get your parts from NAPA or Car Quest.

on those older cars you have to make sure every thing is set right.timing , carb,plugs and point.s also make sure that none of the wires is crossed also check to see if the distributor shaft is not badly worn even the fuel pump could cause you problem.
