Wanted to get some opinions about which bearings to use.

I will use an OEM LS crankshaft that will probably mic out at the proper specs, meaning no previously spun bearings and the journals never turned.

I have been told that OEM Honda bearings have different color codes to specify the different tolerances.........but most of the time, the green color code is used. I've also been told that ACL bearings are just as good, but are always a standard tolerance that matches the OEM green tolerance. I need to know if this is a correct statement. If correct then continue reading. If not correct, then what would be the correct statement?

If my crankshaft mics out properly to meet the OEM "green" tolerance, then which bearing would you use? ACL bearings are about half the price of Honda bearings. Are ACL bearings the same quality as OEM Honda?

 

Its actually depends on the crank and the mains (journal size in the block - crank journal size = free space, free space = bearing thickness + tolerence). Either way, ACLs are great if you plan on rebuilding the engine relatively soon, OEMs if you want it to last. Also keep in mind that these measurements are to the 10,000th of an inch and are very very exact. That and I've never seen an engine with all one color bearings.
