I bailed on Comp years ago.
If you're building a SBC, they probably make fine street cams.
If you want your junk to run like its supposed to, then look elsewhere.
For catalog cams, I only use Isky.
For race engines, I only use custom grinds.

Well, you can say what you want about failures being caused by incorrect installation, but how do you justify the professional engine builders that went from no failures to several failures overnight? Then just about as quickly as the failures started, they have went away. There's still old stock from a couple of years ago being sold that should have been trashed, so we are still seeing a few failures with everything done right.

I don't believe that the cam blanks were the problem, but the white box lifters being sold during that time period. A crap lifter will take out even a good cam quickly. I may be wrong, but anyone heard of an installation with a set of Rhoads lifters going bad during that time period? Same cams, but different lifters didn't seem to have any problems.

Many years ago I ran a 268H cam in my (Pontiac) 455. Really great mid-range, but power flattened out about 4,500 RPM. Cam specs seemed like the power curve should have went much higher before running out of steam. Installed a Crower cam with close to the same specs and the power curve went 1,000 RPM higher before leveling off.

I'm going to take all the factors into consideration but I've already ordered the isky mega 264 with lifters. The xe268 probably would have been good for me with my mild build but why take chances especially at this stage in the build.
