My King bearings I put in said they were made in Isreal. The clevite p series bearings I pulled out of my old motor looked just fine. I use clevite p and h series in my dirt track motors depending on crankshaft. Never had an issue and they live at 5500-7500 rpm..

 

Make offer. I'll ship ;-)

 

Stock48 said to steer clear of the P series which is a bi-metal bearing. The bearings you swtiched to are bi metal bearings. Shouldn't you keep tri metal bearings if you are taking stock48s advice?

 

He suggested those part numbers specifically. I think they are most like the stock GM bearings. He has way more experience building than me so I went with what he suggested. I can show you 10 people that will swear by every company out there.

 

Bumping this thread up for further discussion....

I didn't see ACL mentioned here. Anyone have opinions on them? The engine I am currently rebuilding had ACL main and rod bearings in it. Rods looked perfect, mains had a good bit of wear down to the copper in spots. I will be using a stock crank that will be re-polished; so what I gather from this thread is to look into the King or Sealed Power bearings?

 

so what cam.rod bearing you u guys suggest on a n/a lq4 setup spinning to 62-6300 if possible
