Gary in your signature it shows 55 nomad and 57 nomad, I think you need to "spread the wealth".....ha ha
I also like the shoe box chevys. I have a 55 hardtop now. it took 5 years for me to talk my friend out of it. Since everything else I have is pretty much stock, the idea for the 55 is a alumium LS1 with a 6 speed, and just drive the car in primer and enjoy it..
BUT I am just accumulating parts right now, I have almost everything except the computer, and heads, and some small engine accessories.
There is a long term goal to get all the vehicles under one roof like a barn or airplane hanger, so it will still be some time before it gets put together.
I have had cars with a 6 and they worked well as a daily driver. I bought a 65 ranchero(with a 6) for $200 bucks and drove it for a couple years probably 100k miles, before I sold it for $700. My 64 C/10 had a 6 in it when I got it as well, man that motor ran forever, but when top speed came down to 45 mph, I had to pull it, it has a mean 327 now. I also have a 66 C/10 with a 6 that runs like a charm, although I do vision swapping in that 327 in the future, and building a more wicked motor for my 64.
There is a certain charm to those 6 cylinder vehicles, thats for sure.
