Post your Q-jet equipped E.T.s...

I'm seriously considering swapping my 600 CFM Edelbrock for a worked-over Q-Jet and diving in to the world of Q-Jet tuning.

The driveability & fuel mileage of the small primaries along with the big flow potential of those secondaries sounds like a good combo - especially on a 2-plane intake.

A quick search didn't show a thread along these lines, please post some of your Q-Jet E.T.s. 305 guys don't be shy!!

Let us know what Q-Jet mods you've done too (if they're not too top secret of course).

13.8 @ 99 mph with a mildly camed 383 @ 4600 ft above sea level in a full size SWB truck. I favor a Holley for track use personally that run was just a hey since I'm here and have a spare $12.

IIRC, 13.9@100 with an E4ME on top of a ZZ4 crate.

Don't have the engine OR the carb anymore, though.
