For those that have used either a 440 source or Monlar 4.25 crankshaft in a 400 block, did you have to Chamfer the main bearings? If you didn't, who's main bearing did you use?
They seem to be the only game in town

Yes they do need to be chamfered
Who's crank and main bearings did you use?Mine didnt !!
Maybe, maybe not. I always order chamfered bearings when building a stroker engine since I'd rather be prepared than find out too late that I need them.Thanks guys, but I'm wanting to know DO the bearings need chamfered?
Who's crank and main bearings did you use?
I used Molnar crank and rods in my 400 block and did not have to chamfer bearings. I used Clevite P series 876p full groove bearings. Everyone said i would have to chamfer, but i seen no issues on assembly or now with 4 seasons on the motor.For those that have used either a 440 source or Monlar 4.25 crankshaft in a 400 block, did you have to Chamfer the main bearings?
