camshaft break-in

Coat the camshaft and the bottom of the lifter with the cam lube that came with the cam.

Make sure the engine oiling system has been primed and ready to pump oil...

make sure the distributor is installed correctly and is close enough to fire with in a few cranks..have timing light ready to set the timing ...

make sure you have a GOOD carb that is not going to dump raw gas down the intake manifold and foul the oil....make sure the carb has gas in the bowls and is ready to go..

have the cooling system full of water and does not leak....also have a hose with a sprayer ready to spray radiator if the engine begins to run hot.

as far as springs are concern...I have never removed the inner spring on dual springs....

and yes..get it fired and get the rpm up...dont let it idle...if you have problems..shut it off...

I use 10w-30 Mobil oil with Hughes Extreme Pressure Lube additive...

in the last 4 or 5 yrs I have done at least 6 flat tappet camshafts this way...have not had a problem.
