Jag Daddy Found this cool info link, maybe it will help someone else too
Holley Carb Info

05-04-2004 07:22 PM
tresi I seen a pontiac ventura with a 455 run a 10.83 with a 600 vac sec carb that had no other work other than a jet change. So you reall don't have to worry about the carb being too small. You could slap an adaptor on and a throttle bracket and it would go down the road. Be aware that that type of adaptor doesn't make a real smooth transition to the manifold. What ever carb you use get the manifold that fits it.

Edelbrock does offer a Qjet, but when you said 600 cfm & Edelbrock I assume you mean the square flange edelbrock, Edelbrocks version of the AFB.
Sorry at first I was referring to the regular Edelbrocks. Well the Holley I was referring to came off a SBC so how hard would it be to get it to work.

20.00 for the Holley I couldn't pass it up, it even had an electric choke. I guess I could rebuild it and sell it. The Qjet I have needs a new choke and a I'm sure a rebuild wouldn't hurt. I looked at the electric choke kit for it and it wasn't cheap. Oh well back to the drawing board.

Sudden Psycho 31 to exchange the two, you will need an intake adapter, and sometype of linkage setup and braketry to make it all line up...
throttle , kickdown , etc

Jag Daddy Isn't the Edelbrock a Qjet copy? One of the man reasons I'm asking is a friend of mine has a Holley 600 CFM sitting in his garage for 20.00. I was thinking after a rebuild it would still be cheaper than the new Edelbrock. I might just get it for a spare anyway.

How hard is it to interchange Holley with a Qjet anyway? Cabling etc.

juveteach Stick with the Q jet. SMI Sean Murphy Induction) does a nice re -build on them. For a Q jet he is competitively priced.

stepside454 Id stay with a Qjet, but if I decided to buy aftermarket, it would depend. if its a stock 400, than youll never see 5000 RPMs, a 600 cfm would be perfect, I prefer Holley personally. I wouldnt put a 750 on it unless I plan to run it to 6000RPMs.

87442lover Stick with a Q-jet, they can normally flow up to 750CFM,

600CFM would be strangling the poor 400, you should have a carburator rated at 750 or more for the 400.

jimfulco Me too.

DoubleVision I`d stick with a Q-jet.

Croz depends on how high you want to rev the engine. If you want to rev it to 5500 I would go with a 650.

Holley or Edelbrock? Is 600 CFM enough

I'm looking at replacing my old tired Qjet sometime in the future. Would you go with a Holley or Edlebrock for a 400 SBC?

Also is 600 CFM enough or should I go bigger?
