Thanks, Mike
Not that I know as much as Dragsix, but, ditto on the Brad Penn. That is what the rebuilder used in my 54 3104 Hydra-Matic's 235. I will continue to use it - if I ever get that truck painted, so that I can drive it again (after about 10 years).
However, I will continue to use Rotella T4 (15-40, I think) in the 1960 261 (that I rebuilt back in 1972) that is in my 1954 Suburban.
