what is the best setting in degrees for an HEI 350 4 barrel for a smog check? last year, the tech says I barely passed, I told him that the only thing I had changed was to an HEI ignition from a points setup, he told me my ignition was probably too far advanced, that HEI's don't like barely any advance. Before, my points were set at 8 degrees advanced, so this year I have it down to 6.5 degrees, and pretty lean, and she's running like crap. Well, not stumbling or anything but a pretty rough idle, and she dies when cold. Definitely smells very very lean, so it may pass, it may not. But, is it true that HEI's are generally set closer to TDC than with points?
