01. Our block was an older remanufactured 1977 360, which we found was already bored .040-inch over, for an actual displacement of 367 cubic inches. This used block showed very low bore wear and was simply cleaned up and hand honed for this bucks down build. At the mains we added Milodon studs, and the main housing bores checked to be within specs; Clevite bearings were inserted to accept the crankshaft. We carefully gauged the bearings with the studs torqued to specs and found .0022-.0024-inch clearance—a little tighter than ideal for our purposes, but adequate.
