Put My Motor Back Together....Initial Start-Up I just replaced my rings and had the heads done. I used assembly lube on the bearings too. I was just wondering if there was a special way I should go about cranking it up? Turning the motor over until I get oil pressure with the fuel pump relay removed, then trying to fire it would be the way to do it right?

if you use assembly lube, you must use one like clevites bearing guard, but assembly lube like you use on lifters and camshaft is not good for the main rod and cam bearings. typical assembly lube is not thick enough to protect the bearings on start up. you should use engine oil. this is especially critical on ls engines where you cant prime the oil system before you start it.

dont bother pulling the relay, after my cam install, i cranked the motor with my foot all the way down on the throttle, that way it will not start i used a bunch of lube in the oil pump so it can pump faster, crank it for 5 seconds and take a break and repeat till you see the oil psi guage move, it will move in the crank position even tho all the other guages dont.

I've used coastal assembly lube, lucas oil stabilizer, clevite assembly lube... Even with the cams in these roller motors it doesn't have to be that sulfur looking paste.
The only time it matters to me is on a cam in a flat tappet motor.
I'm referring to Mains/rods/cam by the way.

Most assembly lubes contain anti wear/scuff additives, zinc, and petroleum, and are also thicker than regular oil. Permatex assembly lube, for example, is extremely slick and sticks to amost any surface its applied to without dripping off like regular oil does.

Yes, this is correct, or just pull the 20 AMP fuel pump fuse. I also pull the coil connector plug on each head so that any residual fuel in the fuel line & injectors don't fire.
