First, has anyone had any real world experience with these DLC steel bushed lifters? I am debating on using these in a marine/endurance application where durability is a must..
Second, Is there a special part number for bushed blocks(with small oil feed drilling) such as a BB chevy bodied lifter ?
Third, a suggested where to buy....

I've been using them for 2 years now, used to run Isky bushed lifters until I heard from a very well respected engine builder about BAM's DLC coated lifters and how much better they would be. He's been using them for 3 or so years now in all sorts of high end motors and hasn't had any failures. He told me it may be the last lifter I buy. They are cost less than the Isky bushed lifters. I just put a set in one of my customers motors.

I think they only make 1 for BB mopar.


Here's who I get mine from, he can tell you more about them as he uses lots of them:

I found this on the web Link to BAM website

It does say available in needle bearing, bronze bushed, or steel DLC bushed.
Click on the thumbnail pic of the part numbers.

My next set of lifter will be BAM DLC coated. The only reason I did not use them on the -1 or Victor engine projects was the .210 intake lifter offset vs. Isky's .180. I know, .030, big deal. That .210 offset lister seat is *really* close to the edge in a .904. That said the current 451 project is standard port with standard rocker arm offsets so that will not be a concern.

DLC coating is amazing stuff. I have DLC valve locks in a few applications and they are really easy to work with and still looking like new.

Yes, it is "close". But my mock-up with B1 heads (offset T&D rockers), with 7/16" tapered pushrods (about 3/8" dia 1" from tip) worked out just fine.

No real world experience yet but I purchased 2 sets for a couple builds both dlc coated. Just add BB1 to whatever pn to get the dlc coated. I called Brad directly at BAM to confirm availability and part numbers in mid Nov. Then ordered thru Hughes because I had a few other items to get... Pretty painless. They actually shipped this morning but would have been sooner BAM shut down over Thanksgiving.

Anyone know why there is a Hemi Specific P/N 2016-16-X1 ?

They are taller to help with hemi rocker geometry.
