600 CFM Holley question

There is a guy down the street with a Holley 600 CFM carb for 50.00, it's brand new in the box. Will that be enough for my 400 SBC? Or do I need 650 or better?

I would pick it up no matter if it was for your application or not.
$50 for a BRAND NEW holley 600 is a steal.

If its a built 400 then i would suggest a 650cfm or more..
or as David Vizard said it "If its even mildy a performance application a 750 is the best all around carb you can get"

I went through this same drill (only with an Edelbrock) when I started building up my 350sb, and all the advice I got basically said that 600cfm is fine for normal driving, and in fact it is easy to over carb a sbc. I bought a valve and spring kit from Edelbrock, just in case I want to run it richer, but it seems fine.

hope this helps!

I would recommend a 750 w/vacuum secondary carb nothing less.
I like Holly but every ones likes something different.
Its your prefferance.
I just sold a #3310Holly 750 duel feed, I rebuilt for $125. w/quick change spring kit.
With the extra $50. get a better carb, why waste your money on the bench.
Luv the smell of NITRO in the morning.
