I took one motor apart that had the wrist pins floated with the small end of the BB rods steel on steel, can't remember now if they where six pack or LY rods, knurled for oil retention and clearances I'm assuming/. I'm sure the piston where the old heavy forged TRW small dome "race" 440 pistons shruggy
I've never saw or heard of anyone else using that type of set up since work shruggy
