Home built Comp Solid roller equipped Chrysler B street / strip engine here, @ 451ci for about the past 20 years.
Also 11.0 capable, although it usually runs 11.teens or 20s.
As the dusty engine bay shows, this is a real driver including dirt roads, rain, etc and up until
fairly recently was not ever a pampered garage queen.
I have usually used 15w40 or 20w50, either GTX or VR1, and have been satisfied with both.
I've sent the lifters back to Comp for a rebuild once in all that time as one felt a little sticky on inspection.
When I started out with it I tried old green Kendall GT1 SAE40, the single grade 40 might have been fine
for the summer but it seemed too much for spring and fall, when cold, just judging from behavior.
I did inspect bearings and all internals right around the 10 year mark as well, just to
take a look and see how things were working out. No issues found.
The lifters in this are PN 829 which don't have direct oiling to the roller bearings, splash only.
Some of the same individuals who commented on my similar question back many years ago are commenting today.
I distinctly remember one who will go unnamed throwing his weight around saying this will never work, but here
I am 20 years later with no ill effects.
Getting ready to upgrade to a bigger CI, less radical combination just out of the desire for a change.
So, there's two cents worth from the token Mopar Guy....Good luck with your decision....
