Manual or Ultramatic? Either way, you’ll need new throttle linkages and if Ultramatic then maybe adjustments to the transmission throttle rod.

That said, I am not sure what you will accomplish by such a change other than spending lots of money, work and possibly a couple more horsepower for an engine that was design for 2-brl. You may have a little more gain by installing a high compression head.
