D4B Hood Clearance?
Did a quick sketch at work. I believe extending the kickdown lever in this fashion would mimic the 4 bbl bell crank. Fabricate a metal tab of similar width & thickness to the original lever. (Factory 2 bbl lever shown in red). You are compensating for moving throttle shaft forward, so use that change for the hole spacing. Put a sharp bend on your new tab, so it can't rotate when you bolt it tight to the original 2 bbl lever. Existing rod length should work. This gives the kickdown bell crank lever a larger arc, letting you adjust rod, with out kickdown linkage restricting throttle travel.
