Re: Timing & Vacuum Advance 101
i have the original 302 in my 68z with the off road cam and headers. i can adjust everything after start and it runs great. if i take for a drive say 1/2 hour the idles higher seams everything is screwed up. i have checked for a vac leak none found. could this be my problem. do i need a different can? the distributer was rebuilt on a sun machine but maybe they installed a stock can? hopefully this is the problem.
