Comp Cam ????

One of the hardest hitting cams Ive used in a 360 was the 272/276 on this chart.

Now on a 318 to 390 stroker id like to move up on the lobe chart. Any reason these lobes hit so hard? I know why but is there a better lobe type?

Would you trust one ground from comp today?

What is the cost to have one ground today (current)?

Thanks.
