This car has been in the family from day 1 and I don't have any thought s of ever selling it, so resale value isn't part of the decision. The hartge motor is basically cam, head port & polish computer and hedders. After 280k or driving hard the motor gets tired and doesn't perform like it use to. So it was either a full rebuit including aftermarket cam, which no longer makes it "genuine" anymore or do a transplant and look towards the future for forced induction.
I was on the fence for a long time before I made the decision and I think I fell on the right side of the fence.
