Interesting, I'd never seen or even heard of a bypass on a small block Chevy.

All I have to go by is the 1960 Chevy truck shop manual - on page 8-115 they do show a line drawing of a system similar to your picture. Apparently what you're looking for is called the Bypass Thermostat Housing. On page 8-116 there's brief disassembly instructions under the title: Thermostat by-pass cooling system (Connections for Engines Equipped with Automatic Transmissions).

I tried Google, EBay and Ecklers and don't find anything under bypass thermostat housing. This has got to be a rare piece.
