Another Carb question for you gurus

I know exactly what carb you should have...there are two and I happen to have customers that have either one and I'm sure I could borrow both carbs for a week or so.;) You could test drive them...plus I have the carb that's going on Vic's car that you could try also...
But first how much ign do you have ? type of plug wires..ignition box "if you run one"
the more voltage to the plug the more aggressive the fuel curve you can tune into your engine...
