L79 carburator
We are trying to find a carburator for an L79. We don't need the 'correct' carb, but would like to use one that will work satisfactorily, either a Holley or a QJet. Can anyone tell me what the CFM is for the 68 L79?
The 'Holley' that we have is a 750CFM that needs rebuilding and is way too large.
Thanks

...I've never liked Holley's in place of a Q-jet. A stock airfilter base from a Q-jet car won't properly fit a Holley carb.
...last year I bought a remanufactured Q-jet by Holley in Bowling Green, KY from the local NAPA store for $344 for my '68 convertible as I don't care about a "numbers carb" on that car with I believe a one year warranty.
...it is absolutely beautiful and functions perfectly!!! Very pleased!!!

Just about any Q-Jet (built for cars, not trucks) can be used for an engine that needs 750cfm or less. The Q-Jet is a "demand" type carb...meaning that it only opens the secondaries as much as the engine requires. That's why you can change jets/rods and put them on about anything from 350 ci thru 454 ci.
