I need a lot of help. Brains fried. I have a 65 olds with a 330, Just completed a complete overhaul, new pistons, new cam, new rods, new distrubiter new cap, new plug wires, new carb. Motor will turn over and try to fire but will not run. Have retimed and check my timing several times, have plenty of fuel going to motor, its just will not run, any clue what i am missing? any thoughts on what i could be over looking?
