Basically the best bang for the buck is to put a Hemi in it , the value will increase the most this way
, just because the car is rare doesn`t mean anyone will want to pay for it , I feel the car is worth more with a V8 over the original 6 to most buyers if you are planning to sell it . If you don`t plan to sell do what makes you happy , convertable E bodys are not dropping in value anyway
I guess I need a pic of the K frames to show the difference , the 6 K frame has a different mont pad on each side while the V8 has the same mount on both sides except that the steeering box mount is incorperated on the left side
