Ok big block guru's As you know I have a 71 454. Having a little trouble. When idling if I go half throttle I get a pop back thru the carb. while driving and I accelerate. I get a pop pop pop until I reach a cruse speed.
I have checked timing, valve adjustment, carb(not running lean). The heads were redone less than 1000 miles age. compression is 185 to 190 all cylinders. Idles good, starts good. The plugs show if any thing all cylinders are running a little rich....?????:huh:
