383 A body with B Manifolds?

i just did my 1967 Barracuda from 273 to 383 and tried various manifolds. if you want to save yourself lots of time and frustration, as well as retain p.s. and p.b. get the 1968-69 383 A body manifold PN#2946728 for the drivers side. passanger side can be a B body HP. I finally did, and ended up with a factory looking install!
