Back in '68 I had a Ram Air 400 Firebird. The engine was balanced and blueprinted, included the Royal Bobcat kit, polyloc nuts, and headers. The rear gears had been changed to more user friendly 3.55s. With that combination the engine was still climbing very well at 130 but laid down right on 133 mph (according to the speedometer). Lifter pump up? Perhaps 150 with 2.56 gears.......or a high cliff.
I've heard guys, with much slower cars, claiming much higher top speeds than mine. I'm wondering if Chrysler speedos weren't reading way high on the top end. These guys were always claiming wild top speeds. If memory serves me correctly, GM speedometers were calibrated to be accurate at about 70 mph or there abouts. There is no telling how far off the speedos were at 130. I know one thing, a two mile straight stretch of road gets used up in a hurry at that speed.
