Title: Bearing preference
Post by: 70tp on October 03, 2025, 11:38:37 AM

What is the preferred or not preferred engine bearing now?   About to do a new build and was sent coated kings bearings and my machinist says he prefers others instead. Looking for some input.    Thanks guys

                should be good bearings-coated a plus----if detail needed check each bearing half with ball mic. at 9 points near each end and near center to be sure of fit--crank for taper/radii proper        clearance--like old carpenter measure twice-cut once----(before power tools for young guys info.)--------------oldiron

Personally, I have had success with King's uncoated bearings in an FE drag racing application and, actually, better consistency of measurements than either FM or Clevite/Mahle. The reason my experience is limited to the uncoated version is, simply, that their coated version was unavailable at the time I purchased several set at once of the uncoated and there are still several sets remaining in stock. Any future purchase will be coated "if" available in size and application.
