Fitment was good in all areas. I had to order new pushrods so we haven't made any smoke yet. I will report once I make some passes on it.

Here they are. The DLC coating, what is it ? Looks like a steel bushing with a coating. How does it hold up ? 1090$ here.
https://vincentperformance.com/shop/bam-b-2030-16-bb1/ They make a std bronze bushed lifter. 940 $ https://vincentperformance.com/shop/bam-b-2030-16-bb4/ And a needle bearing lifter. 695$ https://vincentperformance.com/shop/bam-b-2030-16/ USA made. I did not see a .903 lifter on this website. |

Isky red zone, Crower enduremax, and BAM all are good choices. Like dealing with Brad. He will do specials on request. Just got some .903 +.005" with .180" intake offset for SBM.

It looks like DLC stands for"'diamond like coating". Some sort of carbon coating. A lot of the name manufacturers are making lifters using it now.

Well, If Richard can run 7000 plus miles Street and Track and not have any issues with lifters, then I would say your probably pretty safe with Morel. No?

Just my experience from running these lifters. Crower # 66494X903E-16 The Crower lifter were using are HIPPO oiling They also incorporate a .010 groove on the side for oiling from the oil band to the oil supply hole for the pushrod. It's just for additional oiling all through the lift range. The hole for the bearing or bushed wheel is feed from inside the oil band. They are cross drilled and one side is plugged. This definitely has to be check if cross drilled on new lifters. The side facing the lifter bore is plugged during manufacturing. Thank you Mike for pointing this out. From what I understand these lifters are edge oil oiling and is based on clearances in the lifter bores or in my case the installed bushing. We don't run any Restrictors in block or pushrods. So far so good.

BAM has 2 bushing options, Bronze and Solid Steel DLC. Brad mentioned that there are multiple dragweek guys running the Solid Steel.

.040 restrictors might be a good way to go since its not a street engine. |

I fat fingered a reply that ended up on the shaft rocker topic. I'm trying a .062 hole size on my 525 with .903 bushing type crower lifters. Will see how it goes.

I was told .030 was too small for std non pin oiled Comp rollers. 10+ years later still good. When priming the engine I was amazed how much oil shot out of the .030 hole. Took over 10 minutes of priming and slowly turning the engine over to get oil everywhere I wanted. I figure I need to restrict oil to the top end at least some and the HP heads have good drain back. |

This is the best price I have found so far on the BAM lifters with DLC coating.
1000$ Going with them from this guy. |

Instead of buying new lifters why not have Crower rebuild your current lifters ? And they can add the Hi Pressure Pin Oiling option. https://www.crower.com/rebuilt-your-roller-lifters .

I'm trying a .062 hole size on my 525 with .903 bushing type crower lifters. Will see how it goes. I think I'm around .080 feed hole in the bushing. I primed the engine with the lifters removed and there is lots of oil comes through those holes in the bushings. May I ask what oil pressure your running? Thanks
