intake manifold change

3783244 4Brl 62/63 250 WCFB 327,

I would like to use this manifold on my 1972 307ci malibu, will it work? Also, need advice on a carburator for it.
thanks

It will physically "fit" but it won't be much use for a power increase. It requires an AFB-style carb, which can be tough to find except the Edelbrock knock-offs. Most carb guys report tuning problems with those.

Edelbrock Performer intake and a Q-Jet would be a much better performing combination. Addng a 4-bbl. without a cam change is not a good idea, either.
