Question Comp Xtreme 4x4 cam, anyone?

Getting my 400 ready to go, and can't use the old Crower that was in the 351M I took out. Had flat spots on a few lobes. I know that the DEH cams are the standard, but I was wondering if anyone had tried this cam. The engine I will end up with has +.030 bore, stock piston, stock head machined for roller rockers, edelbrock intake, holley 4bbl, headers and dual ex. I will also be adding a new double roller timing set, and the correct springs. I bought a complete long block, so I can get by without the K-kit. I was wondering if anyone had ran one of these 4x4 cams recently, or if someone could help me understand if it would be any better or worse than one of the DEH cams. Here's the numbers I got for it, and the 255DEH and 265DEH to compare:

Duration @ .050 lift Lift w/1.5 ratio Lobe
RPM IN EX | IN EX | IN EX | sep
X4x4
1000- 256 262 | 210 218 | .514 .514 | 111
5000

255DEH
1200-
5500 255 265 | 203 216 | .469 .495 | 110

265DEH
1500-
5750 265 275 | 211 223 | .484 .514 | 110



What would be the pros/cons of the xtreme vs the DEH in my setup?

Thanks in advance
