So my sbc starts up fine idles fine in the beginning, once engine gets hot it starts to mis a bit at a stop sign and when I take off it hesitates but if I float the pedal it will get up to speed and when I’m cruising it seems fine; maybe a small hesitation if I punch it, New plugs,wires,intake gasket ,carb ,fuel pump and filter. I haven’t done any tests on engine. If anyone has had any similar symptoms or any suggestions:;it would be great;it kinda feels like a fuel problem to me, plugs are tan . The engine sounds strong. Thanks again Joe .

how hot is hot? seems that you have tuning to do. i would start with timing. try running with no vacuum advance. there are no exact timing numbers to give. every engine will vary. you need to play with the timing to get it to run right according to the way you drive.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.
