Well, I like to tap the accelerator to close the choke, turn the key and have it roll over and fire and run at at 1300-1400 RPM for a few minutes, big blocks are cold blooded.
I know with the A/C I will need a fast idle cylinoid anyway... so it doesn't stall out when I come to a stop. Six packs came with them so I am going to wire it up for both the A/C and the Choke, it should work just fine.
