i have a '79 z28 w/ a 350.

i know the minimum about carburetors, but still went and bought a edelbrock 600 cfm. i got it for 100 bucks so i couldnt pass it up.

my oe carb has a crap load of vacume lines running to and fro, and i dont know what i should rerun to something else, or what i should just remove. i know i need to keep the vacume advance, and know where it goes. but everything else???!!!! i dont know!!! can anyone break it down barny style, or just a little help works too.

 

Go to this page and click on fig 34 (vacuum diagram for a federal 1979 350):

Then visit the Edelbrock site and see if they list what the various hookups on that carb are for. See if you can correlate that with the connections shown on that vacuum diagram. .

Is that carb a spread bore, that is small primary bores and large secondary bores? That is how the stock Qjet and it's manifold are laid out. If that Edelbrock is a square bore, you will have to change manifold to something that a square bore carb can be used on directly or use an adapter (big HP loser) on the stock intake.

The Qjet is a fine carb if it is in good shape and not one of the later electronic control types. If you want to learn about them, there is an excellent book on them marketed by HP Books, basic carb theory, rebuild, mods, tuning:

thanks that helped out a bit.

but yeah im using the stock intake, and the carb is the two smaller primaries and the two larger secondaries. but i had to use a 3/4 in. riser/addapter. i took off the egr valve, put a plate over it, and the carb wouldnt clear the plate. and i just plugged off all other vacume lines. i just have the vacume advance, pvc, and the booster hose in the back now.

and what could i do about that charcoal canister? i would just take it out, but i see there is a line that runs back to the gas tank... i wanna get rid of all the unessassary crap thats under there... what all can i get rid of and what should i keep?

 

Keep the EGR and charcoal canister. The EGR valve only opens at part throttle, such as when you're driving at a steady speed on the freeway, not at idle or WOT. The line from the tank is a vapor vent line. Leave it connected to the canister and tell your friends that you're doing your part to help the environment. Leave out the part about the big smokey burnout.
