Starting to rebuild the POS HKE 408 out of the 93. Shortblock reconditioned by WATT's SHOP in Lavon, TX. Crank polished, block linebored an additional .002" larger since it was too tight to start with, piston cylinders honed and radiused at bottoms, lifter bores checked, factory stock cam bearings removed and metal shavings left by GM and HKE machining process removed, new cam bearings deburred and radiused and then installed, small ends of rods narrowed/clearance .040" due to rod float causing rub marks on piston pin bosses and then balanced the rotating assembly. Piston rings replaced because old rings were twisted from spiralling them onto the pistons instead of using spreader pliers.
