Had a good experience with Comp Cams tech support.

Scott, refresh me:

Exactly how long did your Caprice cam last before it went kaput?

I'm breaking in a new motor, bbc with a flat tappet...

It didn't die. Just not happy with the noisy lifters. Didn't get any answers from Isky, just shrugged shoulders. They did check them out, but couldn't tell me why they rattle after 5 minutes on the freeway, but were quiet driving around town.

Use zinc additive, or zinc laden oil. Run twenty minutes at 2000 rpm. Take the time to get the timing close before trying to start it. Cranking it a bunch will just wipe off the break in goop. You can adjust the timing closer while it's running. Don't let it idle at all. You can start it at idle, but instantly get the speed up. I just use the idle speed screw. If there is a leak that can't be fixed while running, shut it off, fix it, and restart it.

The numbers etched into the custom grind.



Looking at the cam, you can sort of see the hard anodised look between the lobes!


The old and the new

If you get a chance stop by Comp cam and get a tour of the place," you know i believe in them"

I've had great luck with both Comp and Delta. Both are very helpful and knowledgeable. Don't know about Isky these days but MANY years back I called and actually talked to Ed, who was helpful. Got to meet him last year at Bonneville and it was a thrill for this ol' fart. Good to meet someone still functional and WAY older than I am!
