So I tried with the intial timing at 12 degrees didn't help with the vacuum do think I should go some more. I checked it at 3000 rpm its only about 28 degrees shouldn't it be more than that. Also it wouldn't turnover very good so tommorow I'm going to put a new starter in it. It also seems the left side exhaust seems way more raspier almost annoying compared with the right side. I have upright headers it just seems ones different sounding than the other. I just have pretty much stock ignition except a mallory hei replacement distibutor.
