I always questioned the low speeds everybody talks about, my first b1b in high school had the original 218 (bored .030). We changed the rear end to something from a car of that era. Original 3 speed on the floor. I would run at 65 all the time, screemed a little, but it never failed me. I had several tickets for speeding and "display of power" with that motor. I actualy told the cop once I did'nt understand, "display of power" it is just a flat head 6, he saw no humor in that.
Merle, interesting formula to calculate your speed. I will stick to figuring square feet of wood.
