Have a set of Crower roller lifters and a set of Comp rollers looking to get rebuilt never had this done before should I send back to each company or is there a better choice and is it possible to convert to bushing style

I send my Crower's back to the factory every 2 years. The cost is about 60% from the price of new for my application.

I run Crower needles, always have, always will. Unless Crower gives me a cam and a free set of bushed lifters to experiment with, but I don't see that happening.

I've been running Crower Severe duty with the HIPPO option. Only hurt one, and that was my fault....

You will be OK using the needle bearing type Crower lifter with the HIPPO feature. Mike: I wouldn't hold my breath waiting for a free cam and lifter set from Crower, not going to happen.

The following paragraph is my experience with bushing type lifters.

Given a choice I would take the busing type lifters. One item that will help any bushing type lifter live longer is to use a multi-grade synthetic oil like a 10W/30 in the winter or a 10W/40 or a 10W/50 in the summer months. The clearance between the bushing and the axle needs a lighter weight oil to penetrate and lubricate that tighter clearance/area. Needle bearing type rollers have areas/openings for lubricant to access the axles.

I realize the debate between needle bearings and bushing type lifters goes on and on. Each having valid points, but I am on the bushing side of that debate. Most lifter failures are the result of fault geometry, or the failure of other components, like valve springs, etc. Unfortunately the lifter gets the blame when in most cases it's the casualty of something else failing.

Just my 2 cents.

1. My advice is to throw the comp lifters in the weeds.

2. I ran Crower .842 Severe Duty w/HIPPO roller lifters from 2000 to 2008 in my 468 and never rebuilt them because I got my $ worth having put 1000 passes each on 2 sets. Ran this same lifter in my 522 from 2009 through 2011 before moving to Isky’s .903 EZX bushing lifter for the 2012 season.

Thanks for all the reply’s I’ll call Crower Monday and just keep the comps as spares

Crower prob better than Comp. Crower can rebuild them.

I use the Comp Sportsman bushing rollers in our 565. 500+ runs, .016-.018 lash. Used them on the 632 as well but when the cam broke it killed a few of them and LOT of other stuff.

Ya don't say?!

I wouldn't run Comp in your engine, if they were free. Nothing against Comp, I just wouldn't because of living vicariously through the experience of others.

I did just recently purchase a single pattern Magnum hydraulic roller BBC cam from Comp 11-450-8, I think is terrific power wise. Broad.

That's about as impartial as I can be. Crower roller lifters on the other hand are top 3, not of the same league.

I am surprised at the number of replies and advice provided, without anyone asking the OP any questions about his engine combination.
I suspect there is a point in valve train specs where a bushed lifter makes more sense than needle bearings. I don't know where that point is, and the OP's combo could be at, near, or beyond that point, as he did mention bushing lifters.
With that being said, and all the shade being thrown at Comp roller lifters, I can say there are many thousands of BBC's running just fine, and very reliably using them. Much of it depends on what is being asked of the product. But for a common BBC build with .700 lift or less, a set of Comp needle bearing roller lifters will perform as well as any. I had mine looked at by Comp 6 years ago, they returned them without rebuilding them, said they were as good as new. They are still in my engine, close to 400 passes on them, I check the lash at each valve meticulously, it has not changed at all.
As a wise man once said: "It's all about the combination"

Few bbc’s were running less than .700 lift 10 years ago no mind today. Comp’s standard needle bearing .842 roller lifter has a well earned bad reputation going back a very long time.

I interrupted a long period of success with Crower HIPPO lifters with one set of Comps. That engine was apart in early August to have the needle bearing pieces cleaned out.

I’ve heard many, many similar accounts from friends and competitors with Comp lifters over 3 decades.

I can't comment on the Crowers. But if you have some papers you don't want blowing away, those Comps have found a good use. I use Comp to grind cams regularly. Their lifters don't belong in anything IMO.

Again thanks for all the reply’s and combo isn’t anything exotic just run of the mill 522 bbc with mid 750 lift cam just something to run to the grocery store with and run SC on the weekends

Good video from John Callies. Never had an issue with his product.

To be fair, I have heard they've gotten better. It could be the people in here reporting positive results, are seeing positive results, due to improvements.

I think we're gonna try to use a set of Stewards lifters, in the Blue Chevy II. We still gotta talk to him. We have been impressed with his pushrods.
