650 cfm double pumper spread bore made for Olds….long discontinued. Mechanical secondaries, integral choke. Box lists 66-69 Olds but would work on other years. Easy primary rich and lean adjustment. Fits Q-jet flange on intake without any spacer adapters. Brand new in the box, never had fuel in it….manufactured in the US unlike some later models. Asking $599 plus shipping. PM or text 661-203-6953.

 

Looks like Holley’s version of a Quadrajet, pretty neat carb.

 

My dad bolted one of those on his 71 350 stick Corvette. Said it took top end from 125 to 135. I've still got the carb in a box, he's got a quadrajet on it now. Mechanical secondaries are noticeable fun when you bury it.

 

Just sold it…agreed mechanical secondaries are cool, thanks for sharing. Dave
