Mark McCombs Nova

These are pictures of Mark McCombs Nova and the 250 he and my dad (Mike) built for it. They used a 230 ci Pontiac four barrel intake manifold and dual exhaust manifold with a 3/4" thick 6061 aluminum adapter to match the ports that dad built with his Bridgeport and a die grinder. The thing really ran, Comp cam, 9.5 forged TRW pistons. It ran high 14's at Spokane Raceway Park.
