They work. From what I have seen they work the same if not better than BE. I used them 4-years ago and saw one of my 6.0 from back then and the bearings looked fabulous considering the abuse they took. Bearings cost like $3/shell. Just shows you how much markup BE has. Bearings are big business with these m cars and I am not about to fight anyone on which is best as I don't sell bearings. But you get my drift here.

Good to know someone has tried them with success indeed. I spent a few hours on the phone and email yesterday in order to get more info on these. Seems they show in ACL’s catalog, but several places in the US could not cross the P/N even though they sold ACL bearings. There is an Amazon/eBay seller that has them and they also have a brick and mortar store in Cali, you can get them direct from ACL US, or you can get them from an Australian company. Prices go like this:
From ACL US direct: ~375 USD
From boostproject (Amazon/eBay/shop in Cali): ~235 USD
From M.D. Spares (Australian company): $214 AUS which is about $165 USD....that’s for the complete set.
From the above, looks pretty typical for pricing...ACL US direct is the list, but provide discounts to their distributors (which are listed as sales people on their site, but none have the info on these specific bearings, lol), boostprojects probably buys them from Australia and makes about $100 per set to handle and the faster shipping in the US, and M.D. Spares is getting them locally in Australia from the factory so their price is the best.
Overall, right in line to prices for other non-S85b50 bearings in the world which makes sense as when it is all boiled down, they are just a rod bearing.
The website with the info is aclraceseries.com and it all reads good plus with the copper layer one should be able to pickup the wear with Oil Analysis.
I pulled the trigger on a set from boostprojects for the .001” additional clearance as the M.D. Spares web site stated that there are no returns for international orders and I won’t know the quality of the dimensions till I get some plastigage on them during the rebuild. I might also buy a set from M.D. Spares out of Australia of the Standard size just to see if I need to mix them to get the gaps spot on...heck, if $165 USD why not, lol. If I find I do need to mix them I will have another complete mixed set for a project car or something.
Wish me luck ! We’ll see when I check the gaps once I start this rebuild in a few months. I’ll be sure to post back, but not planning to do this till June so it will be a couple months
