Yes, aware of the issues with todays oils. This blog is a interesting read.
https://540ratblog.wordpress.com/ I did not swap out new lifters for the second cam given they only had 30 or 40 minutes on them and had zero appearance of wear. I think the real issue was that it took me a couple days to complete the second install and much of the assembly oil likely dropped off. Pressure is good and came up very quick at start so I think it was just my slow pace that caused the problem.
I looked at Comp Cams site yesterday. Appears they may be out of stock on the retro roller lifters. Any suggestions for alternatives? I've never retro fitted a roller into a 1st Gen SBC. Do all the roller cams need a button? And does the cover need to be specific to retain the button in place?
