How does the "new" cam compare to the one you're running now ?

Or you just swapping heads and that's the cam in there now ?

My combo was going to be a copy from the start, and Yours was one I was looking at along with 2-3 others here.

Going by ET/MPH/Wt we are very close (10?) to the same HP using calculators. (figuring yours is 2650 w/driver ?)

Only thing done to my heads was to shave them for some compression (where I could have used a thinner gasket too and didn't), Otherwise, minus some fly-cuts, its a stock bottom end.

Or, follow Fast89Stang builds of lots of Cam and Comp....seems to work great looking at the last few motors he was running

This camshaft will require valve reliefs in the pistons to have adequate piston-to-valve clearance. Otherwise it is bent valve city!

That camshaft also has more advance in it than I would run in a LS3. I would run that camshaft on a 105 degree intake centerline.
