I guess I should specify....

When I originally built this 383 I put inthe Comp cams XE284H cam 507/510 lift 284/296 duration.

This was before I had headers...needless to say it was way overcammed and was a complete turd.

I quickly detuned the cam because I was so disappointed in it. I currently have the comp XE262H 462/470 lift 262/270 duration. I think I went a little TOO conservative because of my bad experience with overcamming, but it runs great now. I still wish it would pull a little harder on the street.

I guess what I am saying is that I am little leery of just going to a bigger cam again. The profile of these cams are in the same neighborhood of the cam that caused me problems before..

I may not be sold yet, but......
but I am still listening
