Scat stroker crank main bearing question xtra clearance bearings?
I forgot to mention that you can make a fixture to hold the bearing and put a groove in the bottom half. In fact, a ***** stole mine before I could get it back. I’ve never made another one because I don’t do it all the time. I also made the groove a skosh wider (I say skosh because I can’t remember the exact number) and IIRC some bearings had more of a V shape groove than a U shape. So I ground my tool bit to a nice radius and made the groove what I wanted.
Oh, and according to Clevite, the MS 540H bearings are not full groove except for #5
H-series performance, bearing for position number 5 is full grooved. Bearing position 1 2 3 4 are grooved upper valves and plain lower halves
H-series bearings have a medium level of eccentricity, high crush and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. These bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines. These bearings must be used with most aftermarket Steel crankshafts requiring the radius chamfered bearings, such as, Eagle, Scat, Cat, Callies, Lunati, Cola and many others brands
