Quadrajet on a 440?

i am in the process of rebuilding the topend of my ramchargers 440 - heads reworked, cam, springs, intake. the edelbrock manifold i have has the different boltholes for various carbs. currently the truck has a carter afb which runs fine, but seems to be lacking for cfm when you stomp it. from what i hear, the thermoquads need to be rebuilt around 30,000 miles. i've had pretty good luck w/ quadrajets on (dare i say) chevys, and am curious how a 454 qj would work on a 440.
any suggestions?

Re: Quadrajet on a 440?

First off, if you truck is auto, you are gonna be hooped for bracketry for the kick down and such.. Next thing, I no others think
otherwise, but q-jets really bite..You will have better luck with a T/Q for the 440..at least the cfm and the jetting will be pretty close
to start with..T/q's can go 100,000 without a rebiuld if the rebiuld was done right..I think I would pick a Holley or Edelbrock 750 before
a Q-jet..I am actually moving away from carbs, I am just about finished my Port injection manifold for my 440, now just gotta save up
the 2000 bucks for the computer and stuff.....When it will it ever end..Maxt

What are you using for the injection? I want to inject my Road Runner.

Maxt is right, Q-Jets bite! And the Dodge gods would not be happy with you putting a Chevy carb on that Big Block! Try a Holley, if your motor is stock or near stock (be honest now) a 750 vac. secondary will work best. Don't put a double pumper on a 4x4 unless you are only using it for sand drags. The little performance gain you get from having two accelerator pumps will be noticed terribly at the gas station and your changing/cleaning of fouled spark plugs every weekend! Trust me...I found out the hard way.
