Finally thawed out,got back to work on truck, gas tank was rusty, bought new tank, installed electric fuel pump, cleaned lines, engine has occasional miss from 2500 rpm up. About to give up on points distributor, has anybody had any experience with the cheaper HEI distributor like TSP or am I better off using a pertronix ls igniter. I would prefer to use HEI because it�s all in one unit, I know clearance is problem, but you don�t need to move the distributor much for timing.
