Sorry for the ignorance, and for reviving an old thread, but if people use the heavy duty rear ends like Eaton HO52 with 4.56 gears for hot rods or drag racers, and they use transmissions like TH350s, why the heck is my 71 K20 Suburban so slow? Is it just that the 350 engine can't spin the gears fast enough? Is it just the weight? If I put a 500hp engine in it, will it then 'go fast' with little other modification? (Not that I would. I am just trying to learn how it all works together.) Thanks for any insight! - Marc
