rod/main clearance questions I'll be running a 4" cola crank, in a resleeved 5.3 L block (4.100) with 6.125 lunati pro billet rods, and ARP studs. Does anyone know the clearances needed for the rod/mains?

Greg, The mains need to be .002 or less. Most of the oil pressure problems with ls1s come from guys with .0025 to .003 main clearances. People have been building sbc for 50 years with those main clearances and it is stuck in there heads. The rods are fine at .0025 . I just realized you probably have an iron block...if so you can probably run a little more clearance on the mains.
