how fast with cast iron head 440 and hydraulic cam

I ran a 12.3 @ 109 with stock 2.08/1.74 906's on a basic rebuilt bottom end with a MP .484. 3.73 gear in a 3300lb 73 Duster.

440-C iron Indy heads, bowl porting, 475 cubes, 12.5 1 compression, 750 Holley methanol carb, torqueflite, 4.56 gears, 14x32 slicks, 3180 weight, .540 lift 268 @ .050 cam, 10.10 at 132 mph.

I ran a best of 11.86 (real good air) with a 320 .533 lift mopar purple shaft HYD in a 3800 lb car with ported 906 was a real solid 12.0 to 12.1 car. Lash set so it lightly ticked setting adjustable pushrods is a PITA. Not sure if it was the heads or cam but liked 5800 to 6200 shifts best higher and it slowed down.

Some interesting 440 motors with steel heads..

Yeh... I was just putting my 2 cents worth in about the fact that steel heads are not usually the best way to go. Been there and done that. I had 452 steelies ported and they DID work good. The Eddy's smartened the engine right up.

Steel heads suck they flow poorly they tend to crack and so on. Oh happy days now we have lots of aluminum to pick from better performance way less fuel I have not run race gas since I went aluminum.
