This is my vote
Take out old motor. Put back in a stockish motor. Take built motor and put it into (insert any car here ex. 280z, bmw, volvo, you get the idea) and you will have a ton of fun. Think about it what are you going to do if you get a vette and get bored with it???
I am going to go out on a limb and say sam has more fun in is bmw than he did in his vette.... Probably because it is something different and even though it pretty much has one purpose not being a all around autox and drag car etc he still has a blast like stated everytime he drives it
