If a .842" diameter full skirt body roller lifter did have a .750" diameter wheel the skirt wall would be very thin.

A .700" diameter wheel allows near twice the skirt wall thickness at the critical areas on a fully skirted .842" lifter body.

Yah I know those that went to a .750 went back to a .700 but this set wasn't for a big HP engine. Also if they aren't the .750 wheel or short travel, do you really trust any of the other claims?

Don't care. as I only use stock OEM hyd roller lifters (mild stuff builds) or go straight to a solid roller lifter/Street Roller camshaft set up on anything else roller.
Avoid all the performance issues of retro fit hyd roller lifters altogether. (pump up, bleed down, rpm limitations, unintended noise, inconsistant performance.) (Higher cost).

The 1 hyd. roller motor I built I used Crane retro fit lifters . Turned it to 7k with no problem using K Motion K800 springs. Don't know who made the lifters or if they are still available after the demise of Crane Cams . Dan

Some guy with 1 post bumped this thread and posted a link that I'm not gonna click.

I like oem roller type lifters as well and never have used retro/link rollers(yet), these are the ones I was talking bout back when this post was active https://youtu.be/3sp3RzqBtJo
