I also wonder about the performance of a 2 carb 216 manifold on a 261. Who has some experience
and/or opinion. | | |

Anyway, the 235/261 is bigger. You could ream the 2- carber 216 manifold out if there is enough meat on the casting, since the engines all have the same bore spacing on the manifolds.

You will need to buy the intake rings(?) for the 235 or 261 and take it all to a machinist to have him machine it to size. Cost shouldn't run over $20-$30.
