I know this might sound stupid, but what all do you put assembly lube on and how do you do it? I know camshaft, lifters and the bearings, but is there anything else?

Also, I got Red Line assemby lube from Summit Racing. Is this stuff o.k.?

One more thing, How long can you go between assembly and and starting the engine for the first time?

An assembly lube should be liquid in form so it cant plug anything initially, yet have alot of surface tension so it doesn't run off any time soon. how long..thats just a guess, but once the engine is assembled you can prime the system from the top sending oil to all critical areas, that will stay for a long time. ( I took the injection off my ol mans old asphalt sprint car that had been sittin sinse '85, not one spec of rust anywhere, and everything still had a film on it. everything slid right out. Lifters, pushrods, everything....)
As for what you should lube, thats easy, anything and everything that moves, there is no such thing as too much lube in an engine, especially when its new.

There's a couple of things many people miss when assembling an engine. A couple items are the timing chain, valvesprings and rockers. Soak the chain in oil or cover it completely with lube, coat all the rocker pivots and tips with lube before adjusting lash and make sure the valvesprings are totally coated with oil or lube before firing the motor. Valvesprings need the oil to cool and without anything there, it might be a couple seconds (30 or so) before they have a chance to get completely coated once the motor fires. I worked at an engine shop for 3 years through college (95-98) and saw quite a few motors that had head work done and the rockers were all burnt purple-black.

** edit **

And yes... the Redline lube is good stuff. I use either Torco or Sealed Power's lube. They're both the liquid type that will cling to parts for a long time. There was an assembled 350 in the shop that was left here by the owner for 7 years. We eventually sold it and the lube was still intact. Fired it up and everything was fine. Ohh... also make sure the piston pins have a good soaking in oil before putting the pistons in place or flip the motor upside down on the stand and hose them down.

i cut the top of a distubtor off and knocked the gear off, chucked a big drill in it and use that to prime a motor. i turn the motor with the crank bolt with the drill going-it covers everything pretty well.

Great..Thanks for all the advice. I bought a primer thingy from summit (probably a waste of money but oh well). I didn't even think about the timing chain, rockers or springs.

Thanks again

STP oil treatment is all I ever use. I have been building motors since 87 and I haven't run into any problems yet.

Just don't over oil your pistons,lube the pins good but don't dip the whole pistons in oil,it just gums up the rings when it starts,a little 3-in-1 oil on the bores will do fine.
