I'm getting ready to order new rod and main bearings. What's your take on king's bearings??
Well I ended up going kings on the rods and 77s on the mainsmy son uses a lot of king bearings. But clevite 77's are also good. There is more size selection with Clevites.
I'm about ready to order the King coated bearings for my build...have to find someone that has my undersize in stock...or I will have to order than.
Surprisingly the way the crank is ground and polished makes a difference in which bearing to use too...at least in some circles.clearances and applicable dimensional characteristics are more important than bearing type, get those right and either Bi or Tri metal bearings will live, get those wrong and either bearing material may have problems. A general guideline that I got from one of the PRI show bearing seminars is for steel cranks use Tri metal bearings, for cast cranks use Bi metal bearings.

I'm no authority... There have been several threads on speed-talk.com about this. One technique for cast one for forged. Not everyone agrees but do search over there and you will get schooled.interesting, sounds like you know this subject well and it certainly deals with the topic of this post, please tell us more!

I never hit a disagree button...not on purpose anyway.I'm no authority...
that is what I figured,,,when I saw you hit the disagree button and I was only passing on a statement that contained very general information from a PRI show round table discussion of bearing experts from:
King Bearings and Clevite Bearings,,,

Only used them once before myself...no issues.To date, the only concern we've tripped across with the use of King bearings is the width of the locator tang on some bearings is slightly too wide for the receiver groove where it's to engage. Some file mods were required.
A lot less time-consuming to just buy the narrow H bearings from clevite.lol I got two rotating assembly one time while balance with bearings and all that **** and they sent some regular sealed power main bearings. Needless to say it didn't have any end play!I bought 'em. Used a bearing knife to make 'em fit my full radiused crank..... after I found that I had a full radiused crank...Doh!
