Chevy Small Block V8 Designed and Built by Lee Root, WA, 1980s (VIDEO LINK BELOW)

Lee machined 7075 aircraft-grade aluminum to produce the crankcase, heads, rods, and pistons and there are no castings used in the engine. The cylinder liners are cast iron, and the crankshaft and cam are heat-treated 4340 steel. He used a full size Corvette racing cam for the cam profiles.

Construction of scale rocker arms proved to be the greatest challenge, however he conceded the carburetor and electronic ignition were problem areas as well. Lee developed an electronic balancer to balance the engine and preliminary tests showed the engine to exceed 10,000 revolutions per minute. Several months later more extensive testing displayed the engine would turn at a little over 18,000 revolutions per minute.
