Other than the obvious part number difference, can anyone tell me the physical differences between these two lifters.

Mechanical Roller Tappet Lifters
Mopar Performance P4452919 - Mopar Performance Lifters &
Components –for small block

Mechanical Roller Tappet Lifters
Mopar Performance P4452920 - Mopar Performance Lifters &
Components – for B-RB-Hemi

They both have the V-shape cross bar and look identical. I'm just trying to figure out exactly which ones I have. Thanks for any help

I think the spacing between the lifter pairs is different between a big block and a small block .

Is the oil band the same width on all the lifters ?

Not sure John, I only have the one set and I bought them used on here without packaging. That would make sense though now that I think about it.
