Default Quadrajet specs

Has anyone run across a listing of which jets/rods are used in a particular Quadrajet part number. I'm curious to know which ones should be in my 17059216 carb (79 L48 automatic)

If Lars sees this in the morning, he'll probably know.

Thanks Clem for the info. Any truth to pre 76 qudrajets offering a little better performance on my 79 L-48 or is the limitation the "smog" motor itself. I have a 7045214 that I was thinking of rebuilding and trying. If you have access to a list can you look up the rod, jet and hanger info for this one too. Is there a web site for this kind of info?

Go ahead & rebuild. There is no real problem w/ the engine or carb. The main limits are the ex. & cam.

See:
Why Exhaust is problem for HP on 75-81 http://www.corvetteforum.cc/ubb/Foru...ML/008082.html

Comp 260H or XE256 will fix your auto.
