FWIW, 250 hp 327 heads have the same power pack molding marks as the 283 heads. The intake valves are 1.72 inches while he exhaust valves are 1.5 inches. 283 heads are the same size. You can check casting numbers here:

Glenn gave you some good choices for cams to wake up that 327. What is holding this vehicle back is the 3.08 rear gears and the Powerglide tranny. Switching the rear gears to 3.70 would make a huge difference in how it performs. A TH 350 tranny would also help considerably. I am not a fan of Powerglides. Something for him to think about down the road.Last edited by rumrumm; 02-06-2012 at 09:41 AM.

Looks like I spoke too soon, I have a considerable doubt this site will ever recover and I don't think those in charge just don't give a damn, prove me wrong.
Where is everybody?
