If you are not fussy about gas mileage, Zeniths are just fine. Webers can be great but require a lot of modifications beyond the Redline kit.

That said my MFI cars run fine even after having sat for 10 years. The supply pumps don't like to sit but they can be cleaned.

For a finny, be more concerned with rust and getting a high spec model (230S or 220SE). Make sure all the trim is there and the tail lights are good.
