That's why you have to get the clearances right for the engine you are building. If you put the clearances to loose on the bottom end of a Chevy, you will starve the cam and lifter area. If you think about it, the cam bearing to cam clearances are pretty slim, on either engine type, but the Chevy will die on top if the bottom is not right. That's why when someone asked if 20 lbs is ok, I'm thinking, not.

Or, just switch to a Blue Oval, and forget the silly chebbie problems!!!!!!!!!

I have the 268 xe cam in my mud drag pickup, works great, just doesn't pull as much vacuum as I wanted it to for the rules. On break in I had the stock valve springs and I used Rotella 15w-40 on break-in. No problems. I have 10.25 compression, 781 casting heads good power could always use more though.

Hey Denny, Good to see you are still here. I am nearing my writing distraction and should be back working on the car in a month or so. I just wanted to comment that I had my engine (mild 350) built by a local circle track racer who built many SBC 400s and I requested a Comp 268 but he would not let me buy a Comp cam saying he had too much grief with Comp cams and the Crane was a better bet so I ended up with a mild Crane. There may just be a series of bad events behind his preference but I had to respect his long experience.

I've had a Comp cam in for about 17 years with no problems. Maybe problems with Comp are more recent than that. If I ever needed another, Crane would probably get the nod as many of my friends have been using them very succesfully of late.

Have you looked at other brands like lunati or isky? if not why not? just woundering...
