I have a 1970 402, 60 over with a crower cam..
intake 292, Exhaust 302 also has 9 1/2 to 1 comp. and i am running a Summit HEI dist.
My question is the spark plug gap and the initial timing, I was told to open up the spark plug gap to .045 and the timing for now is set to 8 before
with this combo it still wont idle right in gear (400 turbo) and when you hit the brakes it stalls out, Any suggestions?
