For informational purposes, I have compiled a list of the different brand hydraulic lifters that I have used and compared them to the stock AMC lifters new and old. My primary interest was to see if the Summit lifters were any worse than the rest. Also, I wanted to know if there were any measurable differences in diameter and material hardness. With the help of my man on the inside at AMC/FCA I bought the current stock and performance lifters that is being offered as a Service Parts through the dealerships. He also tracked down many of the old part numbers and they all supersede to 53010574AB which are assembled in Mexico along with most of the Aftermarket ones. Where the castings come from and where they are machined is another whole topic. As I use different brands, I will update my chart. When I can find the time, I will post up pictures etc.. AMCLifterStudy1 by Rick Jones, on Flickr My Amigo at AMCnowFCA went through all the old AMC part numbers and they all supercede down to the list below. They are a service part now and he thinks that are made (assembled) in Mexico now. AMC Lifter Part Numbers by Rick Jones, on Flickr This is the set up I used to measure the Height to Plunger dimension. People confuse the Johnson Lifters. This the original Johnson Hylift Lifter. They don't make a roller lifter for AMC yet but it is in the works. I will call them again and ask when they will be available. Who knows, maybe I will buy the first set..

This article was written in 1979 by Motor Service Magazine. Kinda cool that they used a AMC lifter for reference...

There's never enough money for some people. I'm sure he made quite a nice wage to begin with.

Ok i figured i post this here. About hydraulic roller lifters. I mentioned somewhere that crane hydraulic roller lifters pn 86532 were true 904 lifters. I just actually measured a pair and NOPE! . 903” 🙁. Next i measured a pair of howards pn 91774 .....904 diameter. The howards lifter fits the bore better than the crane. Which is the exact opposite of information on the summit website which clearly states the crane is a .904lifter, and the howards is a .903 lifter, but the micrometers say otherwise🤨The howards lifter is not cut out around the wheel like the crane and just looks more solid, and would definitly raise to a higher lift without opening up the oil galley. ( It looks like the JOHNSON 2511AMX amc hyd roller lifter) wish I could post pictures. The howards “ max effort” hydraulic lifter is an anti pump up design. The howards lifter set was half the cost of the crane set. Dont know whats better in long term but howards sure looks like a better choice at first glance. The howards lifter says “ lifter ,chry/ amc v8 hyd roller” on the box. Crane says “ rf hyd roller lifters- chry b& 426 hemi v8 904 set 16 “ on the box ... so i have run the cranes without any obvious problems. I bought the cranes because the howards lifters have been on backorder since i ordered them in july. Now that i have em in hand the howards might just be the way to go. I’m trying to get a set of JOHNSON hyd rollers. They can be ordered oversize ( .9045) that is much better fit in the amc lifter bore. They make 2 kinds, regular plunger travel(2511AMX)and short travel ,(ST2511AMX) These are NOT johnson hylift chinese parts. They are higher quality american made and a much better part. Trying to get some through engine pro. No success yet. Chech em out on their website. Probably going to be the best choice in amc hyd roller lifters. Definitly not the easiest to get in your hand.

I actually talked to both companies a few years ago and the HyLift are the American made ones. The Johnson are assembled in America with castings from China - At least this is what I was told at the time. The Johnson roller lifter guy tried to sell me lifters in a bad way a couple years ago. I could give them a call and see if I could get you a deal if you like.

Hmm i better re research that. I have been known for erroneous info, , both getting , repeating and giving 😉so did hylift ever develope a hydraulic roller lifter for amc? The johnson lifters appear to be highly regarded, i dont know if thats just hype or not.

Rick, sc397, may I ask, in the above posted chart, is the size of the hole in the Oil Restrictor Disc shown anywhere, or is it only the oil hole through the side of the lifter body and the pushrod cup itself? Thanks

No I didn't measure the hole in the Oil Restrictor Disc. The Oil Hole Dia listed is the diameter of the oil inlet hole in the side of the lifter.
