distributor recurving ?
to recurve it shouldn't be too hard... to get the timing in faster ( iall mine is in by 2100 rpm) you just need to play with the different spring combos ( in by 2200 is usually on medium and one light spring) to get more advance at idle and keep your total you just need to shorten the slots in the advance place some... most guys weld them shut some and fine tune it with a file.... unless iofcourse the thing has an adjustable advance plate in it...
