I just put a Holley 390 on my stock as a rock 272. I put an electronic ignition module in it with new 7mm plug wires and Autolite platinum plugs. Everything is fine. Started right up and runs strong. Not sure about that electronic choke yet but so far so good. Has enough get up and go for me. I have it on top of a 1" spacer. Tons of torque, but it is a torquey old motor anyway. And it looks pretty ..

As a rule, never wire the electric choke to an ignition circuit.  This creates a voltage drop which potentially either causes the ignition module to fail prematurely or just creates a situation where the engine misses due to not having enough voltage to the ignition coil.  An electric choke needs to wired to a circuit independent of the ignition but still turns on and off with the ignition switch.
