Why not trying an 525-cfm Road Demon?
It sports the anular Boosters on primary and is recomended in the 260 to 400 cid range.
(It may sound a bit big for an 235 but with the right secondary spring it should work)
Plus it has some goodies like bowl windows, easy exchangable secondary springs and adjustable float from the outside.
I have such an Road Demon sitting here plus a Clifford 4 barrel intake that will go on the 261 soon.
I let you guys know how it runs.
Plan B is trying out a variable venturi carb like the Predator. No jetting at all. The vacuum signal does it all.

Oh, one more thing Eddie, as far as I know there is no Offenhauser 4 barrel intake aviable for the 235. Only for the newer engines. But what do I know.
