I’m finally going to have my mechanic swap my two-barrel carb to a four-barrel on my ‘73 Fury III. I’m going to be the one looking for a 4B intake manifold. I’ve decided I want to hit up the junkyards instead of going aftermarket. As far as interchangeability is concerned, will an IM from any year 400 work? Will an IM from a 383 work? Any years of the 400 I should avoid? I’m undecided on a carb, as far as if I’ll go with Holley or Edelbrock. Suggestions? Going on an essentially factory engine but mild performance improvements may come. At least till a rebuild is necessary but it’s currently only at 85K miles so hopefully I have a while before I have to start thinking about that.
