I haven't seen a full groove Hemi main bearing set that didn't have the thrust oiling grooves built into them I have seen posts on here by other members advocating using non full groove main bearings on all types of BB Mopar motors including 426 Hemi motors, not me
I can almost hear the discussion when they were spec-ing out the Hemi crate engines... Dont worry, it will be fine to put a thrust bearing in with no oiling grooves, mot people run automatics and we will save a couple bucks....
