Hot air choke tube set and base that bolts to manifold for late 70's Pontiac 400's (77, and 78-79) for sure. Sets that aren't rusted to nothing are tough to come by, and usually the press fit seal for the tube that goes from the base to the carb is sort of loose.

Inline Tube repros the 403 and several other Pontiac motors, but not for the later 70's L78 or W72 400's. With how popular Firebirds/Trans Ams are getting, especially with the Pontiac motors, id say its a good potential market.

An electric choke never worked as good for me as a properly set up hot air choke, even without the heat riser valve, it's still more consistent performance than an electric choke.
