I run them all last season (approx 300 passes). 440 +.030, 13.5:1 Ross pistons, Mopar Performance .590 solid cam, forged crank, Ohio Crankshaft H beam rods, ARP 2000 bolts, 2" Hooker super comp headers, Weiand Team G intake, 1050 dominater carb, Turbo Action "J" converter, 4.56 dana in a 3200 lb E body. 10.38/126.6 in 1/4 mile, 6.56/103 in 1/8.
Like everyone else, I had to clearance for push rods, change springs, retainers and locks. I also had to make a small amount of clearance in the combustion chamber to clear the piston dome around the spark plugs.
Over all, I'm pleased. The best part is the light weight.
