What's an average vac reading for a mild 440. Appears stock other than weiand alloy int holley 650 DP stock 67 74 jets, upped 28 shooters to 31 6,5 PV, cast crank motor, so assuming it will be relatively low comp. It definitely has stock rockers. At idle it reads 16.
69 Dart GTS 440 mopar .590 cam, Edelbrock heads, 3200# best et 6.45, 106.78, 10.14, 132.88 mph, 1.47 60ft best 60ft 1.36

Thanks, the vac reading hardly altered from 1 to 2.5 turns out. Basically, i'm just trying to get it running ok. The thing is, with 17 degrees initial i have 40 degrees max timing, which is a little high, although the motor sounds right. I will try it on the road in a cxouple of weeks, wqhen i get it registered. My Dart has 24 initial with 34 max but that has a .590 cam and a 5000 stall converter.

weld the advance slots up a tiny bit to limit the total timing to around 36 degrees
