    Ok. Not to belabor this point. But I’ve decided to refrain from the needle bearings and stay with a solid pilot bearing. Now I’m given the choice of the original oiled bronze or a ‘Kevlar’ Solid bearing. Other than it obviously being ‘bulletproof ‘ (lol) is it worth the $40 additional cost?

    Stay with the orig bronze oiled. Why recreate the wheel when something already has worked for decades.

    Ok, ok ok. I get it. I’ve ordered the oiled bronze pilot bearing. Nobody carries the oiled bronze locally, only the needle bearing type. That’s why I was questioning the original oiled bronze style. Very good points made regarding the use of original type versus more modern style configurations. In this case sounds like Original is the winner. Thanks for all the input.

    Just to add a bit more to this, my engine builder said to be careful which ones you buy. There are some cheap Chinese knock-offs out there that are bronze plated steel bearings. The bronze wears off and then you have steel-against-steel. Not good.
    Of course he didn't say where to get the good ones.

    Ordered one from Summit Racing made by RAM. They didn’t have much else to choose from.

    This is why I mentioned "non magnetic"if a magnet sticks to the one you ordered maybe you can return it, there are some vendors on Ebay that still have the all bronze.

    Autogear carries the correct bronze.

    I have damaged pilot tip ends on GTO, LT1, and LS1 input shafts. Every one from a roller pilot bearing. I put less then 2,000 miles on an LT1 T56 before it happened and I even verified the tip and rollers were lined up by how far I drove it in.

    Haven't seen a damaged crank from it.

    My experiences with bronze have been just fine. That's my vote.

    Just got the Bronze RAM Bushing from Summit. Bright bronze color and verified that it's non Magnetic. Looks like we have a winner for $7.95 !!!!

    Any GM dealer will have one or can order a proper bronze one.

    Good to know about the summit option...
