The oil pump is an aftermarket Melling M-55 which services most 1958+ small blocks.

The GM #3827369 thermostat housing is applicable to many 1955-68 Corvette applications. However, it was released in the late 1962-1963 period so it was not ORIGINALLY used for any applications prior to that time. There are quite a few very slightly different "variations" of this housing all of which are functionally interchangeable.

The GM #3839175 waterpump casting was used for 1964-E1965 small block applications requiring external by-pass (i.e. SHP and FI). It may also have been used for very late 1963.
