OK, I really want to get an Offy 4x2 with Rochester 2G carbs OR an Offy/Edlebrock crossram with 390/450 Holley carbs (I prefer the side by side carb configuration of the Edlebrock X-C8 over the staggered carb configuration of the Offenhauser manifolds) for my 327 BUT since I am new to Chevy ownership, I know NOTHING about the "streetability/driveability" of either of these induction setups. Any advice/info from you more knowledgeable folks would certainly be appreciated!! I'm also considering the 4 45mm Weber sidedraft carb crossram. THANKS!!!
