I am in the final stages of rebuilding a 235 for my 51 chevy and wanting to put an aluminum dual card manifold on it. I am wanting something that will give good performance and be somewhat period correct for the late fifties/early sixties. The car has a standard three speed and a 55 chevy rearend.

Not really all that interested in an Offenhauser intake since they seem to be everywhere just wanting suggestions on intakes you guys have used in the past and where I might locate one.
Thanks Don
