I picked up this '57 220hp 283 intake a while back and haven't been able to find it a new home. Casting number is 373139. Beside going on a complete resto, is it any good performance-wise? I was curious how well they do compared to a later 60s 4bbl piece. Specifically if it would do anything for my 327 I just put together from junk parts. I do know the carb flange is different, and I do have an adapter to put a regular square Holley on it.
