This is utterly unimportant, of no value to anybody, but I'm curious about you K-car guys. Are you mostly restorers, or are you rodders/improvers?
Personally I am or try to be the latter. I used to help some restorers of early Corvettes, and got fed up with them. Corvette restorers are "correctness" fanatics; the ones I knew, I would not trust with changing spark plugs, but boy oh boy did they know about what was factory original!! I don't know how many bolts I replaced, under the cars and out of sight, because they didn't have the "correct" markings on the heads, and I have worse stories than that. They'd ride around on their pretty cars using the skinny old bias-ply tires that came on them, when using modern rim/tire combinations, nothing remotely extreme, would have vastly improved the ride/handling/braking/steering.
Sure, every marque should be represented by a few totally factory-original examples to serve as historical examples, but after that, why not take a nice design and upgrade it?? EVERY car can be improved. I used to contribute a lot of tech ideas to a Dodge/Plymouth Colt Vista site, now defunct, but never with the intention of promoting restorations of those disappearing orphans; my idea was to upgrade anything that would keep them serviceable.
