Carb question - Holley street demon?

[asickber]

I have been having some issues with the Qjet on my 402BB. I had a mechanic I know that is familiar with the older carbs tell me it's probably too far gone to be worth rebuilding. Was planning on going a different route but found a Holley Street Demon 650 basically new for a good price. Would it be worth looking into? Would I need to make any modifications to run this on my 72 Longhorn or would it even work?
I'm not too familiar with carbs in general.

I'd say if you're running an otherwise generally stock setup get your Q-Jet rebuilt (unless important parts are missing or damaged) or get a new Q-Jet. Nothing wrong with a Holley but any time you change something there are always repercussions, and if you're not a carb guy in general, it's inviting problems to start "customizing".

If you don't mind worrying about fuel lines and linkage and choke and all of that, party on, but I always find it's easier to replace a square peg with a square peg.

Thanks for the input. I don't really want to mess with linkages, etc. He believes the throttle shaft is beyond being able to be rebushed?
Do you have a specific recommendation as to what you'd go with?

IF your Q-jet is not rebuildable, get another Q-jet.

I have never seen a Q jet throttle shaft that was worn so much that it couldn't be repaired.
If this is the case,however, I would recommend getting another Q jet that is properly rebuilt and calibrated for your application.
