cam selection

Well, I do like the comp cams, but I have also used Crane and MP cams without problem and I have not been disapointed in there performances.
The thing with an MP cam is there single pattern cams. I have not used one of those in a long time. The exception was the MP short block that came with the 292/.509 cam.

I'm currently useing a Crane cam in my 318. 216/228-.454/.480 on a 112. It is not much different than a Comp cam of the smae spec. The extreme XE262H rated at 218/224-.462/.470 on a 110.
The Crane idles a bit smoother and quiter while the extra duration spread is very good for bone stock heads. The exhaust ports on the S/B heads are not very good and the extra duration helps offset that. The Comp has less of a spread and works better with ported heads vs. the Crane. But there very very close.

Now before everybody jumps up and down on the comps advantage on the .904 lifter diameter, your wrong and heres why. It says right in the comp catolog, (Go get one and read it sometime) that the HL exteme cams take advantage of the .904 lifter at it's max. Not the Extreme, the Extreme HL.

The MP single pattern cams are fine to use. They just work best with seriously ported heads. (Read race! EAT the prisoners first, take DNA later if your interested.)
