Hi new here , I was wondering about my combo , I'm hoping for low 12's if not high 11's , the car is a 1969 valiant , 2800 stall in a 904 with shift kit , stock 360 magnum with mild ported magnum heads , comp cams xr286-hr , air gap intake , 650 Holley mechanical secondary's , headers , 2 1/2 exhaust with flow masters , and a 8 3/4 with 4:30 gears and 28 inch tall slicks . Just wondering , motor is going in about two weeks , just weighting for my windage tray to get here !!
