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

You're in good shape & this'd be a good opportunity to use the "vacuum gauge method" to find the best initial timing figure your eng likes then proceed with total/springs/vac adv. There's alot of power to be had my getting the dist subsystems spot on live every 24 hour block of time like it's your last day on earth

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. 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
