Builder notes: The block is semi-machined and requires final machining to the builder's specifications: final deck surface (0.011" additional provided), final cylinder hone (4.110" sleeve ID provided), and final OD on the crankshaft mains (0.003" additional provided for the final hone). The cam and lifter bores are finish machined and ready for bearings and lifters. Confirm clearance for all rotating assembly and valvetrain parts, and thoroughly clean the block and verify every oil passage is free of machining debris before assembly and first startup.
