He went on a road trip with a HS buddy of his who is a shop owner, mechanic and sometimes racer to a nearby car show. He drove his Hemi and his friend took his 67 427 Chevelle which is pretty well built with aluminum heads, headers, 4 bolt block, good sized solid lifter cam and a tremec 5-speed. The Hemi is stock except from a hydraulic roller cam and MSD distributor. He said the roads were empty so they pulled up side-to-side several times to have a go at it and the Hemi pulled the built 427 every time, not by a huge amount but a car length or so. Only problem was his speedometer broke at 120 mph. Knowing how well that Chevelle is built and sometimes raced I was a little surprised his basically stock Hemi took him.
