I'm running a gm points style "billet" dist in an FE motor. Looks like they offer a point style can, but it's listed as a replacement part for what I have which only adds 5-7 Deg according to the manual. Set full tight I seek to remember getting 10 and the all in wasn't quite low enough to get all of it at idle.
I spent $50 on the damn accel can, another $20 for the summit one couldn't hurt! Thanks!
