My RR is a 4-Speed with 1970 HP 440 That Dyno at 425 HP and 500 ft.lb torque. It has new hemi Springs on it and what about clamps ??/I do not drag the car and but once in a while would like to spin the tires Mostly just long drives Thanks Tom C.  Your car looks kind of high in the back for stock hemi springs. Does it perhaps have airshocks on it? If not then are the shocks long enough? If they are airshocks or if the shocks are topping out then you will always have wheel hop. GoMangoCuda - I installed new ESPO Springs 'n Things stock springs on my 72 Imperial and it raised the car about the same as TomRR's Road Runner; about 2 inches.
