Dart's in the Shop and Am Already Thinking of the Next Build

So, my '68 Dart is currently in the shop receiving a trans and engine swap with a little bit of an interior upgrade. Basically it's going to become an autocross/road course car with some street manners. Anyways, now that it's in the shop, I'm already thinking about getting another car. Luckily, I'll be getting my Dart back in September. One thing I kind of regret about my Dart is not doing ALL of the work myself. I've done about 75% of it and then would have a shop do the rest because I'd get impatient (wanting to drive it) or busy with life. What I hate most about a build is when I'm trying to meet a deadline and something small goes wrong that sets me back or whenever I do something wrong and have to redo it. I tend to beat myself up a lot for it. So, having a project I won't lose too much on and having a car on the side I can already drive and enjoy may make me more tolerable of another build.

Well, once my Dart is done, reliable, and driving I was thinking about working on another car on the side. With all of the modifications done to my Dart, I'll have a crap ton of parts left over to make a decent cruiser. For instance, when the Dart is done, I'll have:

-273 engine (carb to pan) in need of a rebuild (at least heads)
-273 block
-904 transmission
-7 1/4 rear end with open 2.93 gears
-leafs from the Dart
-complete KH disc brake setup with new bearings, rotors, reman calipers, seals, etc.
-14x4.5 sbp steelies with 205/75/14 tires
-0.870" T-bars
-possibly a PS box and pump w/ bracket (may need to rebuild them, but seemed fine in the Dart)
-a drum-to-drum front end from a '71 Demon
-10" bbp drum spindles
-8 3/4 sbp axles, 10" drums, 2.76 gears, and an open diff (need both axle and gear housing)
-'68 Dart buckets and rear seats (with nice upholstery too)

And various other parts. My goal for this new project would be to build an affordable cruiser using as many left over parts and CL/forum finds as I can get to get the most hands-on experience as possible. No big suspension kits or motor hop ups. Just basic and/or cost-effective improvements (like not cheaping out on a suspension rebuild or shocks). Almost make it like a Lemons or Chump car. I'm thinking an early-A convertible... Maybe even a wagon... or a hardtop if I want to make another "cheap" race car. Out of all the A-bodies, Valiants seem to be the cheapest and lightest with early Darts following behind. '63-66 cars. Paint and body work will probably not be touched. Depending on what I can find for a rear end (8.25 or 8.8 ), I may swap the car over to bbp and sell off my KH and drum spindle stuff (I like discs way too much to keep drums). I've got the "How to Rebuild a Small Block" book and was planning on doing a very basic rebuild for the experience and fun of doing it. Nothing really more than a cam, intake, and carb. I don't expect to make huge horsepower, but to get it above 220 would be great. Rebuilding the 904 (with maybe a shift kit).

Since, my Dart will be running and driving, this would be a side project car I wouldn't really care to put an end date on. Just work on it whenever I can. I won't feel obligated to rush the build as I would already have a running car on the side.

What are your thoughts? I'm open to ideas no matter how logical or crazy they may be. As far as now, it's all just speculation. Lol. :D
