Carbs are a little big for the engine a cam you're running, but it'll work if you jet the primary carb back. If it were me, I'd run the back carb as the primary, gut the front carb and run a slider type linkage from the rear to the front so that you can determine when and if you want the front carb to come in. I ran a setup like that on the sbc I had in a '36 coupe.
