Terminology 101 (References)

over-bore: An engine with the cylinders enlarged in diameter (bored) to accomodate larger pistons thus increasing cubic inch displacement.

overhead: Term applied to engines with overhead valves, but used most often to describe early Ford flatheads (Model A, B, C, or V-8) with overhead valve conversions.

pot: early term for carburetor. (See also Jug).

Quick Change: Immortalized by Ted Halibrand, the quick change was a specially-made center section for an early Ford differential banjo housing which provided two changeable gears behind the ring and pinion assembly. By changing theses gears, the overall drive ratio could be selected for a particular situation.

rake: refers to the forward or rearward leaning stance of a vehicle when viewed from the side.
