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