soft lobes on comp cams

this is a problem that they had a number of years ago. If you break the cam in according to thier specs you should be fine. 262 comp is a good little stick
I prefer the 270, or 292 solid lifter, they have a rumpty rump idle and still enough vac. for the brakes.
I'm new here so I speak softly!!

Welcome to the forum :cheers:
I'll have to take your word on the soft Comp Cam lobes, I've used a few of their cams with great results.

I wiped a lobe on an XE268. Then downsized to the XE262. Knock on wood. :smash:

I'm running a 292S and no problems at about 5K on the motor. They all still measure OK. The 292 definitly gives a lope at idle.

Re: soft lobes on comp cams (Gordonm)

I've got a XE262 and i broke it in according to instructions, no problems with about 5-6k on the rebuild. AND now i wonder, Does GM break in the cams on their new cars??? anyone know???? just curious.

ALL mech/hyd cams should be broken in properly!
If you don't break the cam in properly, they may all have "soft lobes" whether Chevy, Crane, Crower, Comp, etc., etc., etc.!
If broken in properly all quality cams should be fine!

Re: soft lobes on comp cams (Gary79)

Most of the new cars have roller cams, which dont require break in like a flat tappet cam. I have seen flat spots on 70,s L 48 cams that had only a modest amount of miles, my 74 included [34000 miles]. I would bet that these cams were wiped out early in their life.

Re: soft lobes on comp cams (ED DINAPOLI)

So here's where my question ran off to! LOL

I don't know if Pontiac cams are differently built or oiled, but there were a lot of people having problems with comp cams on http://www.classicalpontiac.com and I was wondering about my future plans.
