Hi,

I was lookin at a Holley carb tonight. Here were the numbers on it.

#1850-5
1950

Are these good carbs? I think this is a 600 cfm carb. Anyway, looks like it is in decent condition. What should I offer him for it if I was to buy it? I currently have a 750 Quadrajet on a 350 with a 487 heads, Performer intake, and mild cam. I like my Quadrajet that I have on now. Just wondering if there was anything to be gained performance wise?

Thanks

As far as I'm concerned throw away that Quad.
You can do so much more with a Holley
Of course your fuel mileage will drop with the Holley unless your foot is into the Quad all the time since the primaries are smaller in a Quad,,the secondaries will suck the fuel in like pouring it from a gas can. Well the gas station will like you.
I don't know what you want but a Holley looks alot better on an engine and a smoother working carb.
I've always been told that an AFB is the Best but I will stick to Holley

By the way,if this carb is a good working carb(Holley) it ought to be worth an easy 100.00 if not more but just offer him 25 bucks to see what his reaction is..

I wouldnt go that far... If you work with it enough more can be done with a quad imho

IMO Q-jet>Holley 1850. I wouldn't give over $40 for an 1850 carb, the secondary metering can't be changed without doing a conversion ($$).

Keep the QuadraJet and learn to tune it, the 1850 Holley can't begin to touch it for mileage OR performance. I'm using an 1850 on my 350 right now because it was on the car when I bought it and will continue to use it because it is working "OK" until I do a cam, intake manifold and exhaust change in a few weeks. After I have the cam broken in I'm switching back to a Q-Jet. If you decide to "throw away" your Q-Jet send it my way, I like 'em.
