ANYONE RUNNING A COMP CAM XE262 IN A 340?

Hi Folks

Looking to do a mild build 340 using the XE262. My calculated static compression ratio (used lower compression height pistons than OEM), I am still getting about 9.4:1 with the slugs .0175 above the deck and an .039 head gasket with (iron heads). Using the XE262's Intake closing event occurring at 57* ATDC, that leaves my dynamic compression at around 8 to 1 +/-. So, based on the science, this cam will not work well on pump gas. Looking for any real world experience with this cam. Comp recommended it for my package, even when I thought that my CR was going to be over 10.

I could retard it 4* since it has 4* advance ground in, but I am not sure if it would make the engine a dud.

P.S. I already have the cam.

What say Ye?
