I have a Delco Sl series alternator with a two pin connector and a stud.

Thanks for the help!

I was afraid of that. That 10SI alternator would need to have a wire soldered inside it for the choke. I could tell you how to do it, but it requires alternator disassembly and that might be a bit risky if you're not used to working on automotive electrical systems. 
Using the ignition feed with an oil pressure switch is easier in your case.

Your car probably uses a resistor wire between the ignition switch and the ignition coil, so you'll need to run a wire directly off the "run" side of the ignition switch to get full 12v battery voltage and not draw down your ignition. Run this wire directly to the (+) terminal of the choke with a 5A fuse inline. Then run the (-) of the choke to the same oil pressure switch your dashboard warning light uses. It's a normally open switch that connects its terminal to ground when oil pressure reaches 5 PSI or so. Only when that switch closes (engine running) will current flow and heat the choke. If you like, you could use two separate switches on a T-fitting. 

Nice little simple circuit. It's fuse-protected and current only flows when the engine is actually running.
I cant take out the 1" Hex oil adapter with the only fitting on it in the block because it is basically froze up in the block and I dont want to force it and break it off. I will have to research the alternator trick. I really dont have any other option. I cant find another port to put the old oil sender on the motor. Thanks for the info though!!
