No I wouldn't.
It just wouldn't give me the pleasure to make it worth the extra investment. I'm more interested in looks than performance and I mean the looks of the body and interior and under the hood. I'm not concerned how it looks underneath other than clean and neat. Having said that, I am doing several upgrades to make my '55 project more fun to drive than it would be stock (Ram Jet 350, T56 Magnum, 4 wheel discs, 500 box, Torque Thrust II's, Vintage Air).
I have had several Corvettes over the years. I've had a C2, C3, 3-C4s and my son has a new C6 that I helped him buy. I have the C3 now but I think I am going to sell it and get a C6 after I complete my '55 Bel Air project. My '55 Bel Air is going to be a keeper for life for me.
Anyway, I have no desire to have that kind of chassis upgrade to my '55. When I want to drive a sports car, I'll drive the Vette.
That's my story and I'm stick'n to it.
I guess at some point in this thread you'll explain why you are asking. I hope I am helping with what you want to find out with the explanation of my vote.
