[GTX JOHN]

All our A bodies have 7/8 or 15/16 Cylinders
The large one would not let my elder legs hold
the two step or stop quickly.
We try for 7:1 and sometimes redrill the brake petal
itself and relocate the master if need on several of our
different stockers. Particularly on the two Aspens F Body cars.

You will figure it out.
PM me if needed.
