This is all very interesting, and it seems that we have this question from time to time from relatively new folks on the network.
But that said, it does raise some very interesting possibilities. Even Jay Leno took the body of a 1955 Buick and placed it on a C5 Corvette running gear, complete. I read where he loved to take this creation to the canyons and agrivate the heck out of the Porsche drivers who could not lose a 1955 Buick on their tail through the turns and straights. Of course, Jay also has a jet powered motorcycle he had built....... Talk about "if money was no problem" ....
All this is fun to talk about and speculate about - we all do it in "shop talk" and general car BS sessions. Don't be too hard on the originator of the thread. Let's just have fun with the thought.
BTW, as for myself, I would prefer to leave the SVX as is, however, I don't think there is even one among us that would not like an additional 100 - 150 HP under the hood of our SVX!!
