Malcolm McKeller had a 62-63 Pontiac 421 Overhead Camshaft engine in his car (given to him on his retirement by Pontiac) that had a "single base" Tri-Power carb set-up on it.
So they looked at it before 1962. Tri-Power for Pontiacs went away in 1966 (as we know) but GM continued with Tri-Power on the corvette using Holley carbs.
Single base would have made installation (on the line) easier (Linkage, fuel lines, mounting as an assembly to the manifold) according to MaLcolm (when I asked him, MAY HE REST IN PEACE).
