It is pretty obvious that he is running 2 barrel kickdown bracket and linkage, that is why everything is coming up short.
He made an aluminum adapter to move the throttle cable mount forward, but that still leaves the kickdown linkage arm too short.
Then to go along with his 2 barrel kickdown, he is running a 2 barrel intake manifold with an aluminum 2 to 4 barrel adapter plate under his Holley 4 barrel carb.
2 to 4 bbl adapter plate under 4 bbl carb.
