Re: Cam woes. (Mid-Week light reading)

Just another reason to like the later SBC and the LS motors. Roller cams from the factory. I have just heard about so many flat cams lately.

A couple ideas that help besides the ones mentioned like oil additives.
Motors tend to overheat on the initial start. This cuts int the cam break-in time.
Leave the highest heater hose off when filling the motor. When you get liquid leaking from this hose reattach it. The assures the block is full.
Have the largest 110V fan you can find blowing on the radiator.
Start the motor during the coolest part of the day.

If you are using a modern FI or an aftermarket system like the Holley that requires a O2 sensor be sure to use mufflers or a long extension on the exhaust. Open headers makes for a disaster of the Air Fuel mixtures when the 02 sensor isn't protected from ambient air. It goes farther up the exhaust, with reversion, than one would believe possible. It will mess with the air fuel and make a mess of the initial learn.

It's the splash from the crank that lubes the camshaft, so the rpm is needed.
