Q-jet jetting ?

[brennecke]

I am rebuilding a quadrajet now, and while its apart I was thinking about rejettting. the primaries look pretty worn on top, so I'm not sure which set I have. The secondary metering rods are CP, which should be fine for a street truck .
I plan to use it on a 350 with 300 or so HP. what primary jets/ rods would you all reccomend? How do I know by the number which is lean and which is richer? I can order anything from 66-78 with the corresponding rods. I'm looking for a mix of fun and economy.

call edelbrock and summit, they have these and they can explain it all, also look on www.google.com and search for rebuilding rochester carburetors, there are some damned good perfoermance carb building sdites all over the place with TONS of goood info

edelbrock parts work in rochester carb, same deal,. numbers are explained on sites and by the companies
