So what if it's not numbers matching? The Franks made this '70 Plymouth into exactly what they wished for. The 440 block is date-correct, along with the 906 heads, intake, and CVS Cater carburetor. Inside is a Comp Cams bumpstick, Keith Black hypereutectic pistons, Manley valves, and Comp springs, retainers, and pushrods. The exhaust is dead on, as is the rest of the car.
