Thanks a ton to all those who responded!!! You were right - it was the
starter solenoid. The clicking was definitely coming from the starter, and I
got a new starter and it seems to have fixed the problem. Additionally the
one I took off was obviously the original one or at least VERY old. Not only
did it look like hell (northern car), but the new one turned the engine over
much faster. I never really thought it was turning slowly before, but I
guess a 7:1 motor being cranked by a fresh optima should turn over pretty
fast.
You guys are great, thanks again!
/me hands out cold beers to everyone
Now I will start trying to figure out why it runs like shiat.
