What parts do I need..besides carb and intake..to swap out the Holley 2210 on my 73 Power Wagon 400 ci to a 4 bbl? Are there any throttle or kick down linkage issues?

Thanks

Ok....what I've been able to find out it appears I'll need a 4bbl kick down linkage set up from a van/truck or go with the Lokar unit? Not certain about throttle cable hookup issues.

If this is correct....then are there any good, preferably new, bolt-on 2BBL options? If not, I guess I'll do another rebuild on this 2210 to try to get it running reasonably well.
I have a rebuild kit on the way with a power valve.
