Default Old draw through (SBC) on Craigslist

Not mine. Suspect it's supposed to use a 301T Q-Jet.

Very interesting, does the carb sit on the manifold and connect to the turbo via those flanges and cast aluminum ducting?

the 6 rectangular ports under the carb pad have flapper valves (like reed valves on a 2 stroke M/C. this allowed the carb to run normally when not making boost When boost started to rise, the pressure would close the valves The kit is missing the Pass. side exhaust man. where the turbo was mounted.
