Carburetor question
 

I have a 1972 C10, crate 350. Have an Edelbrock 600 on it and it's junk. Going with a Holley, local parts house has a 600 or 750. Is the Holley 750 too big? Wanted 650, but I'm impatient and don't wanna wait to order one. Truck isn't a hotrod, my daily driver. 60 mile dialy commute to work and back. Thanks!

Go with the 600!
Or fix your eddy with a 40 buck part!
A fuel regulator set at 5 psi.

This, if you're gonna buy a new Holley. It was enough for a pretty warm 327 (1965 Corvette, 365hp from the factory) and it'll be enough for your crate 350.

Thanks for the info fellas, that was my train of thought but was wondering what others had to say. Appreciate it!

Re: Carburetor question
 

Since the edelbrock is crap and you are throwing it away, ill take it.

Re: Carburetor question
 

My understanding is that "Edelbrock" carburetors are Carter carbs? Is that correct?

Re: Carburetor question
 

That's my understanding, I've never messed with a Carter before but I've been told they're cast the same as Edelbrocks and most parts are interchangeable.

Re: Carburetor question
 

Carter owned the original design. Eventually Edelbrock bought the patent and built their own carbs.
Same carb design from the fifties.
Always had one flaw which continues with Edelbrock.
They don't like more than 5 psi fuel pressure.

If you are driving 120miles a day/600 miles a week, I'd look hard at a quality Q-jet rebuild matched to your engine.

"Junk" isn't a helpfull description of the carb issues you are having.
You may very well not "need" to replace it.

Re: Carburetor question
 

60 miles is the round trip, 30 there, 30 back. The reason a Holley seemed a better fit is they seem to look and act more like the old q-jet, while being new and not a rebuild. I'll definitely say carburators are not my strong suit. The Edelbrock is pulling air and running lean, no amount of adjustment seems to remedy it. I have had two ppl I trust tell me the eddy 600's are not at all reliable. It was on the truck when I bought it. My thinking is that if I buy a new one while I actually have ghe money to do so will save my the next 6 mo's of chasing mg tail with it and pouring nickles and dimes into it, which always adds up to big money.

Re: Carburetor question
 

Pulling air like in vacuum leak?

What other mods to your motor?
Do you have a pic of it?

Switching carbs might only make your wallet lighter!

Re: Carburetor question
 

All new vac lines, had to cap off passenger side port, switched over to drivers side port. Might be able to shoot a pic after work. No other mods, pretty much a stock engine, other than an aluminum intake manifold, but it's a generic type, no name brand.

Re: Carburetor question
 

Seeing your position better (with a used unknown carb) but if you have a mechanical vacuum leak or a tuning issue, throwing a new carb on it isn't going to help.

Re: Carburetor question
 

No vac leak all redone this week, tried the timing every possible way I can, that's why I'm ready to smash this carb with a hammer, haha.
