Cool

600 cfm is a good all around size. As far as the brand, it's a personal preference. Personally I find the Holley is easier to work on but my brother is just the opposite. Go figure.

A HOLLEY 750 CFM CARB WOULD BE OF CHOICE ON A MODIFIED 350, SINGLE ON AUTO OR DOUBLE PUMPER ON A STANDARD TRANS WILL GIVE YOU GOOD PERFORMANCE.

Go Holley !!! but it must be made in the last 4 or 5 years. If not you will need to put in a anti back fire kit they are easy to install and only cost about 14.00.

I think rooster's right...with that lift cam going too lean will burn your valves, I would go 750 & maybe step up on the jets.
as far as which one to use? I like the Holley's -the Eldies are real tempermental, but they do work soooooo......

elebrock isn't a carb or a company. Redheads are always best, though. something tells me that you've looked at the board etiquette page and made up your mind to break every rule listed... spellcheck would be a start, mah frend.

Holley race Edelbrock street. 750 is the best way to go. Just depends whether you're driving on the street or using it for racing. I do both so I've got a Holley 750.
Good Luck

ive got a engine similar to yours 70 nova and i run a holley 600 vacume secondaris and it has more power then a 750 because 750 is too much fuel, plus if u drive on the street stick with a 650 or 600

edelbrock are nice, holleys are nice, since your manifold is spread bore, like a edelbrock carb, and a holley is a square bore, with the holley youll need a adapter plate .

Well put chuck!

[quote]with that lift cam going too lean will burn your valves, <hr></blockquote>

Using a 600cfm carb will not burn your valves. That would be like saying if you step on the gas too light you'll burn the valves. Incorrect jetting could cause problems but you can jet a 600 carb to run as rich as you want and .488 lift/234 duration is not the hairiest cam on the planet. I would suggest a 670cfm Holley Street Avenger with quick change secondary springs or the 750cfm vacuum secondary will also work nice. Like chuck said, Blonde...brunette...redhead?

[quote]since your manifold is spread bore, like a edelbrock carb <hr></blockquote>

Loudmalibu, how do you know if it's a spreadbore or squarebore manifold?
