'74 air cleaner - before and after

I bought a 71 Cuda in 84, with no engine, and a Company advertised an NOS 440 block with pistons and rods for $250. Place was 3 miles from my home. I bought a 440 forged crank, had every thing balanced and ran it. The point I'm trying to make is I started to list all the parts and prices for my info. The buying became so rampant that I just gave up trying to keep a record. So I've added a Gen 2 Hemi, Tremic 5 speed, new interior, be cool radiator, another 6 pack 440 and the list goes on. Probably have $75,000 invested and still not done.
Holy crap. I always wondered how/why some guys could put that much $$ into a car, then sell it for far less than they had into it. I mean, other than just for the satisfaction of bringing something back to life.
I figure I will end up putting more into mine than I had anticipated (but not $75K), and I'll either end up really liking it and keeping it, or selling it for a bit less than I end up putting into it. It's growing on me...
