King Race Bearings? Ever hear of them???

I think they are king acular bearings. They are used in racing engines from nascar to top fuel. The race bearings are expensive. if they are in good shape and the bearing clearance checks out ok then your good to go. But never a good idea to install used bearings with a new crank.
 
Thats awesome! They have never been used! I bought the shortblock from TMD in california I got it shipped for less than 600 and it has probe dished forged pistons, stock rods and crank but the internals were new and the block was prepped so I couldnt pass it up...thanks a lot though!
