Comp Cams Kauffmann HR224: 275/281 224/230 .502 .510 112 LSA This is a sensible performance grind that will work will with power brakes, A/C, automatic, etc. Jeff said he uses it in his daily driver.

The 110 LSA cams are best used for engines with compression below 9 -to-1. I am using a 112LSA cam on my 455 build with just over 9-to-1 compression. Is this Comp Cam's XE274? Interesting note at Comp's website with regards to the cam specs, " Valve Adjustment: Zero Lash Plus ½ Turn ". I know you installed the heads and adjusted the valves.
I previously had a solid roller in mine that was 236/242 @ 0.050 on a 110 LSA and made .600 lift at the valves with 1.65's, and it wasn't all that nasty. Being a roller, it didn't have as much overlap - plus it was in a 461 so the extra inches tended to tame it down some.
