Roller rocker choice for HYD rollercam/for High Miles-Full life

Hi Yellow Rose,
I mostly have lifter examples in pairs going back into the 50s. For doing custom block machining
on a Bridgeport like I described a few posts back. Like 40yrs ago on the outlaw sprint GM stuff.
I made a custom riser for my mill back then so yes, I can put a 440 on it and even do the cam
bores, with the crank in line with the table. Way before CNC. Manual 1-of setup. Used to tease
my brother about cnc way back then, as of now he has 36yrs cnc for the areo space industry
doing ultra small parts for satalites in extream hard to machine alloy's. Like a internal threaded hole in titanium, size 0000-120 thread pitch. Back then it was "wow-175 beeeutiful precision parts
all wrong instead of 1
"Then the outlaw guy's for other engine's wanted .904 1" inch mushroom tappets over the GM .925's, anything over .940 would pickup the next lobe. On to mech rollers.

To answer your question, I have pairs for referance all these years.

Take care,
Rick
