Argess ... one thing you might look at on your initial/full timing . The guy at 4secondsflat.com makes a set of bushings to replace the MSD dist. bushings . The largest MSD one is an 18 degree . ( 20 degree initial and 18 degree = 18 total ) . He makes a 14 and a 10 degree . I am playing with the 10 degree and have 26 initial and 36 to 37 full at about 2700 rpm . So far , the plugs show no detonation and the low end has cleaned up pretty good . No run on or hard cranking when hot either . I can`t remember ... do you have an MSD distributor ?
