optimal bearing clearance...
#2
as far as i know you should want factory rod and main clearances and then ask you piston supplier what they reccomend for a PTW clearence also reference in about .003 if you are going to spray a big shot of the juice
#3
Rods .0018 to .0025
Mains .0020 to .0027
stay on the tight side if you use nitrous to keep from beating the bearings to death and use a good oil
no less than .005 on the thrust
ptw depends on the piston material/skirt length - whether the block is iron or aluminum - types of power adders etc. - anywhere from .002 for a cast piston to .005 for a forged nitrous application (actually seen applications with as much as .009)
Call our engine builder and S.A.M. graduate Heath Clayton if you've got anymore questions.
