Well I am some what on the other end of your situation. I have a 88 5.0 almost where you want your 92 to be some day, and let me tell you that it has taken me 6 years and more money then I paid for my Mach 1 to get it that way. If you have a really good place to store the 92 so it does not get all rusted up and banged up while you are gone, and you are willing to put the time and money it takes to get it where you want it, then keep it and enjoy it. I know that my Mach 1 is way more enjoyable then my 88. Sure my 88 is faster, but the Mach is the whole package. If I had it to do again, and had my Mach 1 at that time, I would have never sank that much $ in my 88. Good luck on what you decide to do.
