newbie cam question, dont beat me! ;)

[cstraub]

Just be sure if you use the flat tappet profile you use:
cam lube on cam and lifters
Use GM's engine break in lube, available at GM dealer
Use a light 10-30 oil and over fill the crank case with 4 more qts.
Don't let the engine drop below 2000 rpm for 30 minutes.
We lost 2 lifter mfg. a couple of years ago and these things have been giving us fits.

Ok, I will bite Overfill the crankcase with an additional 4 quarts of oil? I have never heard of anything like that before. Never to old to learn a new trick

I think it's a good trick. 4 more quarts would be a pretty good "splash" oiling system to get that camshaft through break in. And the GM lube. Been doing that for years. You ought to hear the Ford guys cry when I tell them to use it. On the big cams, we used to do weak springs to get throught the break in period.
But personally, I would never do a flat tappet cam anymore. Just too many advantages to a roller.

Yeah, it's common practice for circle engines during break in. Puts the crank and rods in the oil and throws it on the cam. This is just fine during camshaft breakin and you won't hurt anything. Do not run the engine on a load like this. . . just break in.
Just had a customer loose a cam this weekend. . .he told the guy take the heavy springs off and use a set of break in rockers. . .didn't do it. . .now the cam has 10 lobes and 6 round circles.

30Min! Oh my neighbors are going to f'ing love me! I dont plan on use a flat tapped it sounds like to much of a pain in the ass for my application.

Reason #98 why to go roller. If you cheat that cam on break in..it will go flat. Trust me.
