New Valiant owner in SoCal

225 /6, Offenhauser mani with Holley 4bbl, auto 3 spd, unknown rear-end.
Note: Trying to switch out that Holley with a carter 1bbl. Any suggestions on how to get my hands on one?

Vanessa- 1bbl's are pretty common. Better is the "Super Six" set up; it's a 2bbl...be sure to get the exhaust manifold and kick down as well.

Not sure how you'd swap it onto the old bellcrank throttle set up on your rig if it is still there (imagine it's not since it has a 4bbl on it now).
