500cfm too small?
I think I know the answer to this question already but I figured I'd get your thoughts. I thought I had a 600cfm all this time and just now decided to run the p/n and found out it's only a 500cfm. I have had some carburetor issues and until now figured I just needed to tune the darn thing. I guess I had better step up to a larger one, huh? Suggestions? have heard (read in another post) that Demon makes a nice carb designed for the ZZ4 motor, although I don't know what p/n it is...I'll keep looking. Any other recommendations? :confused:
Thanks everyone! :thumbs:

:iagree: or Holley 650 dp with mech. secondaries, if you go with a Speed Demon you would probably be best going with a vac sec. as it is more forgiving if over carbed. It seems that the Speed Demons flow more than there comparably sized Holley's or Q-jets.

Re: 500cfm too small? (Tom73)
Thanks for all the tips guys!
Really, 750 for a BB or SB?
What do you guys think of this one?

A bit pricey but is it worth it?
Thanks. :cheers:
Too Small?? Well, stock was 750 cfm....so, yea, maybe a little small :)

Hmmmmmm... I've got an Edelbrock 1406 (600 cfm, vac. sec.) on mine, but it's a pretty mild combo-so I think it's adequate for my setup. Would the same hold true if I did a heads/cam swap? Since we're on the subject...(I don't want to hijack your post MM)

If the is carb. what I think it is perfect, I hear that they were going to start selling carbs. prejetted for certain crate enigines.
If this is the case then Berry Grant has tuned in this carb for your specific engine, it don't get much better than that.
:party: :cheers: :hurray: :party:
By the way they are suppose to start selling the six pack setup again (three duces, 3x2) again. If they do then they need to preset them for crate engines too, this is stuff gear head dreams are made of.
:rant: :D :cool: :cheers:

Re: 500cfm too small? (Tom73)
Your right, but they're doing it or will be soon. It kind of makes me wonder what they set as the baseline they used.
If they based it on with headers I think they would pretty much have it nailed down.

Holley 670 !!!
I do not have one of these but I wish I did. I may get one for the 79 though.

Re: 500cfm too small? (Ganey)
Thanks everyone. I ended up purchasing a "Crate Demon" from Summit. It's supposedly spec'd out for a ZZ4 and it's 650cfm so hopefully it will work out good for me. The guys said they have sold a bunch of them and have had no complaints (not that they would admit to a complaint but they are usually pretty good to deal with).
Thanks again for all your suggestions!
