"I'm thinking of adding a split manifold to my '65 235 chevy"
Probably a typo but hopefully you are aware that 235 production ended with the 62' model year except for a minor handful of exceptions.
I have the 2 x 2bbl setup mentioned above and don't particularly recommend it. Better to do a small 390 CFM Holley 4bbl on a Howards intake. Just less hassle all around.
