LA 360 Engine refresh?

Compressions look fairly consistent. If it was me, I'd fix the leaks and drive it, and start socking away money for a crate motor. Trust me when I say you won't be on such good terms with your neighbor after a few weeks. You'll be under pressure to rush things, and despite your best intentions you'll have oil and antifreeze all over his floor. A pre-run crate will take far less time to drop in...when you're ready...and by then you may have your own garage to work out of. I'm building my 340 now (again) and the cost is likely gonna equal or exceed that of a crate motor by the time I'm done. I'm doing it in small chunks on my own time in my own garage, so that's OK. If I was in your situation I would be throttling WAY back on getting in too deep.
If you are really jonesing to get your hands dirty and get right in there with the alligators, I might suggest finding a good core motor and start building it to your specs. It will take up a whole lot less garage space than an entire car and you can put a drip pan under the engine stand. Just sayin'...
