carburetors

[Uno99]

Well I got about the same milage so far with my qjet to holley 600 carb swap.  My qjet was in really bad shape though.

I was getting about 15 with my 305 and out of tune E4M Q-jet.  I expect better with my 350 and Edelbrock #1406 (yes, I cheaped out and decided to stick with carb over EFI).  I would think the difference between a dialed-in Q-Jet and a dailed-in Edelbrock couldn't be more than 1 mpg.  (i hope)

By the way if you want to rebuild and tune a Q-Jet.  Pick up a copy of Doug Roe's Rochester Carburetors.  A valuable tool for messing around with these carbs.
