I can't answer this fully, someone else may be able to chime in. My clearances are: mains, .0032-.0035 Rods: .0032-.0033. I guess you would consider that loose. I was limited on my options because of my crankshaft. The main clearances are fine IMO. The rods are about .001 larger than optimal. I was locked-in because I am running a left over Funny car Nitro crankshaft. The rod journals already had extra clearance ground in and were .031 under. So I had to polish and run. The mains were .023 under and I was able to grind to -.030. Oil circuit is stock other than .040' restrictors at each lifter bore. There is TONS of oil to the valvetrain.
