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
