November 6, 200222 yr comment_18365 I've heard of these kits before, but i've never seen one. Does anybody have any pictures and/or does anybody have any pros or cons on them.

November 6, 200222 yr comment_18371 Haven't seen the complete kit being sold in years. Used to be MSA and Impact Parts also sold the complete kits with carb linkage and all, however, MSA still sells just the manifold.

November 6, 200222 yr comment_18385 You can get a 4 bbl. intake from Clifford Performance. Use a Holley 390cfm carburator and cable throttle linkage. It's a pretty straightforward conversion.
