I have a B+M 174 Dick Landy setup. As you can see the thermostat housing was welded shut. I dont run a thermostat.
The Landy intake is an Offenhauser daul quad manifold that had the 2 carb flanges milled away and an aluminium plate welded in. That matched the opening and bolt pattern of either the 144, 162, or 174 B+M superchargers. Landy had several revisions and updates on their butchered intake manifolds. Most of the 144 and 162 units retained the the use of a thermostat. On some of Landys 174 units an offset thermostat housing and/or a snout with clearance for the upper radiator hose was used, mine didnt have either of these provisions. Landys design and craftsmanship was questionable at best. The lower pulley mounting setup was a poor design. The amount of welding done to the manifold resulted in a warped unusable piece that required the blower mating surface and the runner face to be machined before install. Robert Landy, Dick Landys son, was unpleasant and arrogant. Totally impossible to deal with on the phone. No wonder they went out of business.
