This came from I guy I know on the HAMB:-
For any really serious GMC guys out there, Crower is running off another batch of roller lifters for the 302's. They only make these once in a while so when they are gone, the're gone and you have to wait until they see enough interest to run another batch.
Part number for the lifters should be 66274T989-1. These are groove type lifters, not link type and require modification to the lifter bores to keep them properly oriented. The tool to modify the lifter bores is the drill jig 66575X989-1. Dave & Matt at Crower have been the ones dealing with this so they would be the ones to contact with questions.
I believe the Chevy 235 / 261 takes has the same lifter bore so I can't see a reason these wouldn't work for them too.
Anybody here that's an Inliner member can pass the word on.

Can anyone tell me if these lifters are interchangeable b/w Chev and Jimmy sixes?
