Hi Milt,
If it were me and the motor was to be just for temp use I'd part the 2.4 out and find a decent running motor. You'll spend more rebuilding this motor than you can sell it for when it's done.
There's an add for a running 2.7 in the classifieds for $1000. It's in San Diego. That's less than what it will cost to rebuild this motor.

I don't know if you've rebuilt a 911 motor before so maybe the 2.4 is your trial run but really they're quite easy. Nothing near the level of difficulty that you've already experienced with your body work. It's just a matter of disassembly, inspection, sublet machine shop work, buy parts and reassembly by the book.
Waynes book makes it really simple because it's laid out so methodically. Even if you've rebuilt motors before Waynes book is still comes in handy just for use as a mental checklist.
I think you're gonna really enjoy rebuilding that 2.2S and posting here. The rebuild forum is great. It's more business than the tech forum and contains a ton of info.
