Question Weak 302

Howdy all,
I just picked up an '87 Clubwagon w/a 302 in it. The gizmo that looks like a bulb just up from the 3/4ish tube running from the exhaust is busted. The engine as a whole is running weak. I've yet to check compression (lack of tools), but the plugs and wires need changed.
Any ideas on where to go after this? I can bum the comp tester in a bit, but being the first V8 I've had a chance to fool with, I'm close to stuck.
Any theories will be welcomed!

Could that be the HEGO? the Oxygen sensor? Does it have wires running to it?

Check the timing it should be at 10 degrees BTDC.

I'll check how the O2 sensor looks tonight. I am wondering about it's condition due to the air tube running to the exhaust pipe being broke.
I can check the timing, hopefully, on Friday. It was my expirience on my '90 F-150 that w/the timing, the computer controls it. It's worth a look though.
Thanks again for the ideas. I'll keep you posted as best I can.

My O2 sensor looks to have 3 wires. 2 white, one black. All seem to be intact. I would like to clean the contact though. I've still to check timing.
