66 valiant with newer slant six

Hey guys working on a checklist. I’m looking at swapping my 170 for a 225. If I get a 67/68 up 225 I would need to get a bigger flywheel, swap over the oil pan and pick up, and make the exhaust pipe a little longer. Could I swap my intake and keep my current carb/intake and throttle?

No need to replace the flywheel - just machine the hole bigger so that it fits a later crank. Bolts are in the same place. Did that on my old 65 Valiant with 170 when I swapped in a mid-seventies 225.
