535window: I'd rather have the 4barrel. Used for a long in L6 and liked a lot, it was a holley 390cfm and a clifford, but the engine was a 250.
Don't know if there is the same advantage on the 235, but the 250/292 clifford manifold is soo much better than the offy, that I'd give them a call before buying one from any other brand.
