Install and Break In Procedures for New Camshaft Help

The oil slinger goes in front of the crank gear, not behind the the cam gear.

You are correct on the rocker shaft placement. Oil holes point toward the valve springs, down and to the outside of the engine.


Just be careful as you have already stated removing the old cam and installing the new one. Inspect the cam bearings thoroughly before you install the new cam. If they need replacing, it's better to know now than later.


On the big block, you can get by much better without removing the oil pan first. On the small block, it is damn near impossible to do it right without oil pan removal. Very straight forward. It's just a hunk of stamped sheet metal.

Make sure you have a very liberal (think Nancy Pelosi) amount of break in lube on the camshaft. As a plus, I also use the Comp Cams break in additive dumped in the oil pan too. Choose an oil that is high in zinc.

I like to use 2500 RPM as a BARE MINIMUM RPM for break in. I vary between 2500 and 4500. The more splash, the better. Above all, do NOT let it idle within the first 15-20 minutes.

Not sure, but I would GUESS the 268 cam calls for the 911 single spring. It should not need anymore than that. But use whatever spring Comp says and you should be fine.

One last thing. I would not do all this work without degreeing the camshaft. You don't have any idea where the cam is in the engine without doing that.
