David Wheeler started working on this T speedster when his son, also David, was in grade school. That was a while ago. Here, the younger David did most of the driving. The '23 Model T block is topped with a Rajo overhead valve cylinder head and overhead exhaust-"true overhead." A Model A crank and cam were adapted to the block, fed by a single Winfield carb. The aluminum body wears a grille shell from a '15 Maxwell.
