Getting ready to put the engine together. Would it matter what is used as assembly lube as far as bearings? Have a tube of lubriplate, or would it be better to just use engine oil?

Personally I always use lubriplate assembly lube.

I used the thick red stuff that is very stringy. you'd think it was melted sugar the way it strings out like that. it sticks to the surfaces well and you don't have to worry about it dripping out before engine start.

I used a black paste on the cam though...moly/graphie maybe? I don't remember what it was.

machine shop said they do it the same way.

i used GM EOS on bearings and piston skirts and pins. Also on lifter bores (i used it everywhere-its got zinc- its what motors crave!). but assembly moly lube in good too. cam break in lube on cam. moly lube on bolt threads.

Sounds alot like the stuff I used on my bearings. I'm almost positive that STP makes it...

I used the cam lube that came with the cam, and I coated the cylinders with auto-trans fluid.

Engine assembly lube, sometimes a little white lube, and wd40 for the cylinder walls/rings.

Lifter bores should be lubricated with a very light machine oil, not a thick lubricant like assembly lubes. They may keep teh lifter from spinning as they should. yes use a good lube on the faces and cam but not on the sides.
wD40 is not meant to be a lubricant. It is a water/moisture displacer. I have seen nuts actually tighten up on the threads as they get warm when using WD40 as a pentrant.

Crane engine assembly lube for bearings, wrist pins, rockers, pushrods, etc. Cam lube for cam and lifter base. 30w oil for rings and lifter sides. Lubriplate - door hinges. May be fine on a very limited basis, but I've pulled apart customer engine (failures) that the stuff plugged the filter up, causing lube problems and bearing failure. The red assembly goo is more filter friendly.

I used the EOS on the lifters. its sort of a slightly thicker oil but not so thick.

I made sure that the lifters would turn in the bores without a hint of binding and that they woul slide into place with only gravity.

Then after priming the engine that EOS gets washed out a bit with engine oil but you get to keep all that wonderful zinc in the pan!
