I'm going to be putting new lifters,rocker arms, pushrods and a new cam in a 350 sbc. What is the best way to break in the new parts ? Does anyone have any tips ? Thanks !

I have always coated the cam and the bottom of the lifters with a break in grease from GM Goodwrench. Soak the lifters in tranny fluid for a day or so, then assemble the motor. This has never failed me.
This is just my way of doing things however. Others will surely have more good ideas.

make sure you have the timing set close to
what you need before you fire this puppy up.
it helps to have some help on this. once the
car is started, bring rpm up to about 2000
and let it run at 2000 for about 1/2 hour.
that will break in the cam to the lifters,
make sure your timing is close to what
you run.

On the tranny fluid, I know it gets into the lifters faster and better, therefore filling them up. this makes it so they don't run for a second or two with no lub. I know also that if you go to the parts store or just gut a distributor, you can take the shaft out of the center and use it as a primer when attached to a drill and stuck in the end of the oil pump
