hi all just out of interest, does the black box that sits next to the vaccum pot on the distributor make that much difference to the idle on 383 2bbl.
i was looking through my manual and i found that my car should have a ground lead off the carb to this black box which retards the timing at idle , so off i went to look at my set up, and guess what! it aint there! got two screws an a thin strip of metal though ha! any input would be cool bye for now trev
