When I first got my heap running in 1982, I had a pretty mild 440 in it.
-.040 over 440 with flat tops .055 down the hole
-Crower "Monarch" 280H cam(224/224@.050, .460/.460, 110lsa)
-Stock 906's with upgraded springs
-ex manifolds with crimp bent exhaust pipes for a 383(no H pipe)
-Original Torker with a 650dp Holley
-12" converter
-3.23's
-g50-15 bias ply tires

At Sacramento raceway it would run low-14's at mid/hi-90's.
Best ever was like a 14.06....... And it never broke 100mph in that configuration.
