Yeah my 70 Swinger340 buried the speedo too. And with 3.55s. That would be 6400 rpm. And with 3 screaming teenage boy passengers in there too! Me? I was trying to get the floor-mat off the gas pedal.
That car was close to the most ill-handling performance car I ever owned. Too much motor for the factory chassis,and too much car for a 17 year old, and most especially,too much verything for those E70s. G60s weren't much better.
By 73 there were no original powertrain parts left in her. Second engine, second diff, third tranny, second D/S, probly third alt, second starter, third clutch, second set of springs and shocks, second shifter,and something like 14 tires.Sheesh, what a money-pit.
Oh wait, the carb and intake were original.
I survived.
