'70 Dart 392 Project; what direction?

110% jinxed myself.
Got throttle cable installed on pedal side, I ran the attachment a little higher than factory to try and get more travel out of it. But factory pedal travel only opens the LS cable throttle body maybe 50%.

With the extra travel needed I dont know that modifying the pedal linkage itself would be enough. I might have to work something on the throttle body side. Either a secondary lever that compounds the cable travel, or a smaller cam on the throttle body itself. Pedal travel I’m guessing is about 1.5-1.7” and the throttle body needs close to 3”….

Gonna think on this one! Any ideas?
