Would someone please indentify the following parts for me and provide an idea of what the market value might be: Intake Manifold #3919803; Thermostat Housing #336790. Thank You

GM casting #3919803 was used for all 1968 Chevrolet small blocks with Rochester Q-Jet carburetors. This included all 1968 Corvettes with small block engines. Although it was used for only one model year, there were a LOT of these manifolds made. I would say that it would be worth in the $100-150, range, though. Of course, it would only be worth that to someone restoring a vehicle that needed one. For someone just needing a 4 barrel cast iron manifold for a small block, it wouldn't be worth over $25. These things of a variety of casting numbers are too plentiful.

The GM casting #336790 thermostat housing was used on many 1974-76 Chevrolet engines. This included 74-76 Corvette. This housing has one NPT fitting for a sensor. It was discontinued many years ago and replaced by a later PRODUCTION housing with 2 NPT fittings. For earlier installations, one of the fittings is plugged with a pipe plug. I don't know what these might be worth. I wouldn't expect a whole lot since there are a lot of them still around.
