Getting fed up of high-perf , being happy with less

I understand. Anything you do for a long time gets old. Sometimes just taking a year or two off helps.
I was heavy into circle tracking when I was younger, some pitting for a friend, some driving my own. Spent a lot of time either in a shop or at the tracks.
Then I became a trucker and just plain wasn't home enough for that stuff.
Now that I'm retired and saved a little money strictly for a hot rod, I'm not so sure I want to. The old bod has taken a beating, my back is pretty bad, knees aren't great. Brain still says do it, body says maybe.
I have a nice shop with a lift and lots of tools, I can weld decently, have done plenty of fabricating, even put a Cummins 4BTA into an '81 D150, which I sold because I just couldn't get motivated to finish the body work.
I had a 50th anniversary 'Vette 6 speed that was so much fun to drive, but I was barely able to get in and out of it due to my back.
Sold it for a nearly new Challenger that was so nice I was afraid it would get damaged every time I drove it, I just couldn't enjoy it.
So I bought a southern 2011 Ram Hemi 2wd R/T single cab short bed for fun. It gets 22mpg on the open road and pretty decent around town. Headers, exhaust, lowering kit, does ride a bit stiff, but I don't mind. I'm a truck guy anyways. That was meant to be my hot rod. I have a Viper 6 speed ready to go in it this winter, am debating a cam swap, and now find I have 3 hernias which need surgery.
I'd like to find a decent roller cheap and put my own motor in it. I really can't do much of anything until next year now, so I have time to search.
