I use Federal Mogul AKA sealed power.
If you are interested in a brand new in box set of -10 main bearings, they are $20.00 shipped.

The matching rod bearings can be picked up almost anywhere.

sorry guys. I was at work when I posted this. I have very bad dyslexia and couldn't write everything I wanted to. To add to what I posted. The crank is a cola crank 20 under Manning's rods all are 10 under . the rods I am using are carrillo with sps wmc7 rod bolts . my other question is the crank is for a to bolt main block. I know I need the conversion from to bolt main crank to one pce main block adapter. Has anyone here done the conversion. If so did you use the GM parts or any aftermarket parts . the GM part is a round 270 I found one on eBay item number 260126056654 18.00 can't believe this is the same part other places are around 40 and 50 wondering why GM is so high. Is it the quality. If you have done his conversion I would really like to hear how it can out. And if there's any tricks to installing or adjusting someone told me you need a installation tool to align it up. I'm trying to get the best bearings for this crank and rods. Read a lot of posts. But none were using this crank and rods. Would love to hear any comments anyone has with good or bad experiences doing the conversion and their choice in bearings whether they use p,H. setting up motor for 7000 rpm and around 400 horse LE 2.2 cam, motor is a 95 lt1 block.

Sounds like you are a little confused on the terminology. I believe you are refering to the rear main seal in your last post. FYI '85 and older Chevy small block motors used a 2-piece rear main seal (prone to leaking). '86 and newer small blocks used a 1-piece rear main seal and as a result, the back of the crankshaft is different to accomadate the seal. I believe you are using an early style crankshaft in a later block (LT-1 block), therefore you need a conversion kit to allow you to run a 2-piece rear main crank in a 1-piece rear main block.
Most standard blocks (1 or 2-piece rear main seal) use main caps to hold the crank in the motor that have 2 mounting bolts. Some "hi-performance" blocks used 4-bolt main caps (just on the 3 inside mains). You can also have a 2-bolt main style block converted to a 4-bolt main block by machining the block to accept new, 4-bolt main caps and then having the block align-bored/honed at align the new main caps and block. Hope this helps clearify some of the terminology.
As far as bearings are concerned, there are lots of quality manufacturers as mentioned above. I typically use Clevite 77 bearings. In my most recent build, I used MS-909HX for the mains and CB-663HX for the rods and they were coated.

Hi Pat,
Sounds like you have super quality rods and so they will not egg-shape when at high rpm. Then you want the H-series bearing from Clevite because the H-series is designed for rods that do not distort at high rpm.
The P-series bearing is for a stock-ish rod that will egg-shape at high rpm.
For the 2-piece rear crank that you have, yes you are correct. You need to get that rear seal adapter. It's a 2-piece to 1-piece rear adapter.
I don't know why the GMPP adapter is so over priced. It's probably not any better than the less costly ones.

it's just scary. Trying to find some other places that making these adapters. Supposedly Barroso makes one just don't want to go cheap and have any lakes has anyone here used any. if so what brand.
just wanted to say thank you to boosted and guickss for all the good info you shared. I did a little measuring the guy that gave me the crank and rods gave me a flywheel it's to a Oldsmobile with 166 ring gear. It bolts perfect to this crank it's drilled for a 10 and 11 inch clutch does anyone know if they can replace the ring geer to the 168 and come ring gear the highth of this flywheel is 13 1/4 wondering if this is the same high is a flywheels with the hundred and 68 tooth ring gear. It would be great if I could modify this to be used if so with a 11 inch clutch would it fit in the stock 95 six speed Belle Helsing when I pulled the tranny to do the clutch when I first got it there wasn't much room from the body to bell housing a bigger bell housing I'm wondering if it would even fit without modifying. And do you recommend I get a scatter shield being the motors will be built for 400 hp. Any good clutch recommendations being I may be using a 11 inch clutch instead of the 10 1/2 can i go a little later on the pressure plate. The couple people recommended spec 2 Spec 3 any input would be grateful. I'm really sorry about the spelling and grammar. I'm using Dragon NaturallySpeaking due to have really bad dyslexia. And when I dictate my mind sometimes wonders this is what it sounds a little jumbo. But I really appreciate all the help you guys are getting. This is the last straw in my build once I get this figured out I'll be building the second block I have for this build and then be ready to pull the motor.
