Anybody know much about the Tattersfield Dual Chevy intakes? I just picked one up that was told would fit a 235. First thing I did when I got home was set a 2BC on top...didn't fit. So I grabbed a 216 carb, and it slipped right on. For the hell of it, I set it against an Edelbrock 2x1 235 intake, and it matched identically. Sort of confused now...
