What would be my best options for a throttle cable and kick down cable for this swap? This is currently a 2 barrel so I’m assuming that the stock set up will not work on the Demon carb and aftermarket 4 barrel intake.

I’m gonna go with a street Demon carb don’t know whether to go 625 or 750 and I’m leaning toward a aftermarket clone air gap.
