Hey Hotrod haven't seen you around for a while. First thing i would do is replace the rod bolts with new ones, prefrebably with ARP 2000's or L19's. The torgue specs on these bolts would be 65/70lbs with Zinc type lubericant, the head studs would be 65lbs with Zinc type lubericant. The mains would be 65 lbs center and 45 lbs outer with zinc lubericant. Both rods and mains clearace at .0025/.003 runing 20/50 oil. No less than .002 on any of the rods and mains.
