the larger core means that it is a longer distance around the lobe
the larger wheel rpms slower
i did bot know comp had .810 roller in retrofit lifters
anyone else run them?
AAFIK johnson made all the retrofit lifters
512-- is yours a roller block with stock replacement lifters?
It’s what’s in my 372”
The comp solid body roller lifter with the .800 or .810 roller. I had a buddy run these for over a decade in his drag car, 2 different engines. I figured I’d try them in a street car?
