Challenger flathead V8 was made by Dick Pretel, of CA, in 2001. The only part of this engine typical of the Challenger V8 is the crankcase; everything else was machined from 7075 aluminum, steel, and stainless steel bar stock. The crankshaft is bolted into the oil pan then bolted to the crankcase. Two plates on the bottom of the pan are removable to access the connecting rods. The water and oil pumps are machined into the front housing and the fuel pump, radiator, fan, and starter are located in cabinet below. The pistons were designed by Dick and fabricated by Dave McMillan and the crank and cam were ground by Roger Slocum, The engine measures 14 inches long, 7 inches wide and 10 inches high. Dick’s style exhibits his red thermoplastic distributor cap and trim.
