Hello - I'm new to this forum. I've found lots of great advice on here so far, so thanks for that!

I'm trying to figure out which bearing shells to order? - Crank is a standard (soon to be 0.25 or 0.5 under) Cosworth YB with Crower Sportsman 5700 rods in an old Pinto block. The engine was built 10+ years ago and has Clevite bearings in it. I can't find replacement Clevite rod bearings so am looking at Mahle from Burton. Trouble is what to use with my set up - YB or Pinto bearings?

Also as this is a full-race roller cam 2.0 NA run to 8k+ RPM should i use the Mahle Motorsport bearings? Or is there a better option?

Cheers
