Just installed in my 95 LT1, a Comp Cams "Extreme" LT1 Camshaft, 218 / 224, .495 / .502 112 LSA. Do I really need to rev the engine for half an hour to break the cam in????

 

You dont have to break in a roller cam......just change the oil after 100 miles or so and inspect it for anything unusual.

 

I gave mine's a 10 minute break in period. Doesn't hurt a thing.

 

Yea, and you might want to change the oil after 10-15 minutes when first starting the car.

 

I'd do it. Won't hurt anything, so why not have the extra reassurance? JMO

 

I am going to run mine for 20min at 2k or so then drain the oil.... Is that all that is needed? I am also going to run non synthetic for 300miles or so then put in synthetic... My question is how long do i beed to go untill i can really get on it?

 

There really is no reason to break in a roller cam like that. You do want to change the oil/filter though since theres a good chance dirt may have gotten into the engine when you had it opened up. When I did my cam I let the car run for about 10-15min. and then changed the oil/filter. Then I drove it for about 100miles and changed again.

While it in not necessary for break-in as with a flat tappet cam, you should keep the rpms up for a bit. The lobes are only oiled by splash and the higher rpms make that happen.

 

so can i get on it right away?

 

I would just take it easy until you change your oil/filter at least the first time. Its not that your worried about wear patterns on the parts themself, its dirt and other stuff that may be in your oil and running through the engine.

so after i run it for 15-20min and change the oil i should be ok?

 

What's your hurry? Better to at least get a few good heat and cool cycles into the parts. They will be stronger that way. Maybe (hopefully) you put in new valve springs, too. They need to be heat cycled several times as well.

 

I think i will go ahead and go with my original plan of a few hundred miles of easy driving and change the oil after 15-20min and after a few hundred miles. just to be safe.
