Most of the blocks I machine are for .904 and .937 lifters Most common ones I sell are Morel and Bam lifters, The Bam lifters with the steel bushing is the way to go IMHO There sizing is spot on best I have seen so far.

The other plus is on the blocks with a 55MM Cams the oil band is .092 lower so you don't have to run special bushings.

Nice info, just put a new motor together and didn't go Bushed just because the engine builder didn't think we needed them because the cam isn't as aggressive.

Not a fan of bronze bushing lifters have had calls about failed bushing lifters no particular brand but the jury is still out.

On the other hand I do like the steel bushing lifter so my customers have a good results with them.

In most cases of lifter problems guys are using an .842 lifter where they should be using an .904 or .937 lifter. And most heads are over sprung by a lot.

First of all, Bronze bushing is not the materials being used...

Second, the so called bronze bushing lifters, Isky in this case work great! I have used a set of their .842's with 350 plus on the seat and 1050 open for over 350 runs on an older combo (12 degree 632 BBC), no issues, no signs of wear!

Currently using the same deal except .904's in the my current combo, going on season 3 with the same lifters! Pro20 headed 632 with 375 on the seat and 1100 open.

I never got anywhere the service life from other Named brand lifters with needles running similar combos & cam lobes!

As for steel bushings, no experience with these but if they work too, that's great for all racers too!

Isky EZX .903 in both my engines, lifters in the door car engine have been in service since 2012 with bushed lifter bores, since 2016 in the dragster engine with non bushed lifter bores. Both engines have new lifters for the 2020 season.

ISKY lifter are a nice lifter but when it takes 3 sets to make up one set for sizing that sucks, Do a search on ISKY lifter sizing.

stop measuring!

So my old .842's with all those runs on them that are still like new, one set from isky.
Same with the current .904's. Maybe they send their seconds to you only?

I am just saying I see the total 180 degree opposite of what you post with Isky lifters from both performance/durability and sizing.

The lifters in my dragster engine were taken out of the box and dropped in the bores by me and somehow lasted 4 seasons, over 800 passes, won the division championship in '18, finished #2 in the division in 19' and #4 in the world. I say Isky's EZX .903 lifters are very good! Now they have been retired from duty and are back in the box for spares.

Same with the Isky .903 needle bearing Redzones in my 565 bracket motor, dropped right in and never had a failure in 4 seasons. The bushed .903 EZX in my blown TD were just dropped in the aluminum Brodix block and over 100 runs so far without any issues. I have had them out of the block 3 times for inspection and just put them right back in.

BUT with deep pockets!! LOL. How many bearing half/sets are in the drawer. Oh 25 or so.

Funny since I have two or three times that.No cost,so how does that relate to deep pockets? LOL

Isky wins. Will be ordering set next week. Hey that big government check will cover it. LMAO

Bam is excellent on there sizing compared to ISKY. I have ISKY lifters sent to fit up when machining and sizing lifter bores. A lot of sizing problems with ISKY. They are going to a new vendor to take care of this problem so sizing should be much better in the future.

I machine quite a few blocks for 5MM cam cores and Brad Miller owner of BAM lowered the oil ban on his lifters .092 so it can be used with 55MM and 60MM cam core so you don't need a special bushing. His steel bushing lifters with the DLC coated axle are probably the best lifter out there.

Most guys posting here don't build there own engines or have any measuring equipment to measure a lifter they dump them in the bores and call it good LMAO

I did talk to BAM. They have a untested lifter for Hemi. Untested is kind of catch. Then I am notorious for testing untested ideas and stuff. LOL

I was pulling trigger on Isky's.Now wondering about the BAM's since so many high recommendations. Maybe talk him into me being test vehicle would be added fun.

Been using Crower .903 hippos with great success. If worried about running .900 lift 13
00.+ open pressures I would prefer the Jesel upgrade for a piece of mind.

Just out of curiosity I measured all my last set of Crowers and they were all exactly the same.

Always have been. Crowers are excellent. It would be difficult choice, to buy anything else.

I run Crower bushed lifters and they have not had any problems.

With that said my motor is a SBC and you are running a Hemi style and you said it have lifter oiling issues. So what works really well on my motor may not be for you.

No oiling issues for lifters. It just does not have pressure fed oil to lifters. Does have issue every now and then to pushrods if you don't take care to lube them first start up of day.

As for lifter choice. I have a set I am testing to see how they work out. If get enough runs on them to tell how well they hold up under the preuure fed deal.

So what? Does not have "Pressure fed" oil to lifters but there is no oiling issues. Right. Have to lubricate pushrods at first start up of the day. Why if it has no oiling issues? If there is no oiling issues then you can run what everyone else does with no problems. But they are all pressure fed. In your second post here you said "The oiling issue is one I should have pointed out in OP. My Bad." When YOU say you have an oiling issue I am trusting you have an oiling issue.
I guess others with similar blocks have problems with lifters?
Point is if it does not oil same as Chevy and others what works well on them may not work as well on yours.
My Bushed Crower lifters require good, clean oil or they will not last. Like someone else here already said find out what others with same block as yours are running.
