BILLET THERMOSTAT HOUSING LOW PROFILE -20AN SBC BBC SILVHOLDEN Aeroflow AF 64-2334S

Suits Small Block and Big Block Chevy (V8 1955 to 1986) and Holden V8.

Designed to accept traditional thermostat (sold separately AF49-1136).

The Aeroflow Performance low profile billet thermostat housings are designed as low as possible to ensure clearance on various intake manifolds. This low profile also allows a direct plumbing path to the radiator. Machined from T6-6061 billet aluminium with a male -20AN outlet. All Aeroflow Performance thermostat housings feature an O-ring base flange, as opposed to using the factory paper style gasket, this ensured a superior leak free seal.
