My 468 has been on an engine stand since last July, after a full rebuild and because of the Comp cam in it I am worried about loosing a lobe on the cam and having to rebuild again.. So what was (is) the problem with this company's cams.Is it the cam or the lifters?
Has it been resolved? I do not see any more cam issue stories. The cam is a EX262 that was purchased last July when all of the cam issues were voiced on this site. Other than starting the motor how can I tell if it is safe.
I called COMP CAMS and global warming is more
of a problem than their products :mad:

If you have plenty of break in lube on the lobes, lifter bases, fuel pump lobe (if your using it), and distributer gear, and you have the valve lash set correctly (zero lash plus 1/2 turn) then you should be fine to start it up and break in the cam.

Be sure that when you start it up you already have oil in the filter to aid in quick pressure build up and you run the engine for 30mins at 2000rpm fluctuating it a couple of hundred rpm's every now and then to vary pressure and splash of the oil.

If everything is done right it should be good.

Gene,
I really do no think that Comp's products are any more prone to failure than any of the other manufacturers. It is just a matter of numbers. If you purchased 500 Chevrolets, and 2 Fords, you would see more failures in the Chevrolets because you have more of them. That does not mean that they are any worse than the Fords. Same goes with Comp. I bet if you did a survey, more people use thier cams than any of the other manufacturers, mainly because of thier aggresive advertising. If the guys here on this site purchase 200 Comp Cams cams, 5 Lunatis and 5 Cranes .... the chances are you will hear about more failures in the Comp Cams. I have only had 2 cams fail in the 17 years I have been in the machine shop business .... one was a Comp, which I use almost exclusively, and the other was a Crane.
Stop worrying and get the thing started smile.gif

Also some other tips...
add GM's EOS to the oil and PRELUBE throughly (rotating the engine) just before starting.
I also like to use Valvoline Racing 30 wt oil (high zinc content) in crankcase.
Pour some gas into the carb bowls thru the vent tubes (assuming a Holley here).
Best chance for successful cam break in is have the motor start the instant you hit the key.
Have a large fan available to place in front of the car to help cool the radiator during break in. Fresh, tight motors generate heat.
