I left my ac pulley off my damper, as my ac runs off main belt. Use the ATI hub to center the front cover. Set the cover in place and start the bolts but leave them loose. Install the hub fully. Once hub is installed, the cover seal is centered. Only aligning you need to do after that is at the pan rails. Make sure the cover is level at the pan rail, meaning equal contact on each side. You can put the cover on crooked and the cover will stick down on one side or the other .180” or so. Level it at the rails and your golden. I have an alignment tool set but I’ve never used them. The LS is almost foolproof for seal alignment if you install hub or complete damper before tightening cover bolts.
I got your PM, but I haven’t had time in the last couple days to get you an answer. I haven’t been in the shop, just too busy with work.

This is what we use. After spraying the **** out of it for a season the bearings and everything still looked brand new. It has extra zinc in it. You might want to check it out.

There are different Supreme 7000. It has to say Racing Oil and Extra Zinc just like the picture to be the right one. They have it in different weights. You can buy it from Amazon.

Penrite has .168% zinc and .096% phosporus... these 2 together make up zzdp antiwear A good racing oil will have the same or more phosporus and you cant have really good anti wear without phosphorus.... Thats how im reading it anyway... Penrite racing is a good oil for production engines , its not for built engines

Apparently it's better than the penrite.

Its all about the ZZDP, anti wear.... Read any article about oils for built engines, higher spring pressures, lifters, rockers, cam...
As i said my machinists told me of a few different builds he'd done where there was lifter failure, rebuilt engines and lifters failed again, then changed to a proper racing oil, and problem solved. I dont know about you but the way i look at it is " do i spend an extra $150 to potentially save my $30+k engine from future failure"
