Hopefully whatever plan you choose at the end there is satisfaction. Once you get the car running keep your projects small and your car on the road. I have a soon to be 10 y/o son, twin 5 y/o girls, and a 13 week old baby girl and little time on my hands for messing around. I however will find time somewhere to intercool my KB this winter because I have an incredible wife and I've learned that my best time to get car work done is after 9pm when all of my kids are tucked in bed. I'm up at 4:45 am for work so I have to make that little bit of time count. I'm sure you'll figure out a balance and it seems like you have a supportive wife which truly is the key.
P.S. Fellow Stangnetters,
I have an ex-wife up for adoption, high miles, well fed, moody and sometimes bites, free to any good home
