Lookin to go with a 600 cfm holley 1460 1850-3. Would this be a good carb with a kit and for only 60$?

 

On this note too..besides cfms because everybody has their own opinions..but what would be a good model of holley 2 or 4 Bbl carb to run with the offy c intake..efi dual manifolds.?

 

I was running a Holley 1406 600 CFM on my 460, and it was just about perfect, but I did wind up replacing it, as there was something going on with the floats and it kept loading up and gushing fuel. Maybe it was my particular carb, who knows, but keep in mind that it wasn't anywhere close to brand new, and a re-build would have probably done it some good. In my opinion, a 600 would be a little too much for a 300, 390 CFM would be about perfect for it. If it were me, I'd try to find an Edelbrock 1403, or a comparable 500 CFM 4 barrel, one with vacuum secondaries would be even better. This is such a small (in terms of cubic inches), low-revving engine, that you don't need a whole lot of carburetor for it. But again, that's just me. But, for $60, why not? If it doesn't work out for you, you at least gained a carburetor on the cheap that works well with a variety of engines.

Again, something with vacuum secondaries would probably be best if you're going to be doing alot of street driving with it. In my experience, Holley carbs are finicky, and I've always had to stay on top of them as far as tuning is concerned, and I don't really have alot of personal experience with Edelbrock carbs. I hear lots of good things about Quick Fuel (I particularly like the adjustability on the Quick Fuel carbs) and the newer Demon carbs, but those carbs are kind of spendy. Just my $0.02.

Well..here's how I look at it. When your looking at displacement and such..many guys run 600 cfm on a 302..so why give up 600 cfm for a 300? It may be a 6 cylinder..but that's ONLY two cubes smaller. And with the extra stroke of the 300 it shouldn't matter a whole lot. Mind you..600 should be about the max a person should go. I've looked at everything from holley 390s and edelbrock 500s..but it seems for the price and reliability of holley..I could have one cheaper..put a kit in..and be done. Then again like you said..I could make the engine fall flat on its face. I guess my reasoning for posting..is well..I'm newishh at the 300 scene...and it seems as if everywhich way that something won't work then guys come up and say it will. Then if something works..a handful will say its junk or there's better ways. Either which way..I guess the best way is to mind out ourselves haha.

 

Well, when you do the math, assuming 83% volumetric efficiency, it comes out to 324.2 CFM required to run it, and 390.6 CFM assuming 100% volumetric efficiency. So, a 600 CFM wouldn't be my first choice for a naturally aspirated engine (though I must admit that I'm thinking about using a 600 when I put a turbo on mine), but if you're getting it for cheap, run it. That 1406 has vacuum secondaries, and they'll only open up as they're needed, and I don't really think that it'll be revving high enough to open them up all the way on a regular basis, so you might be able to get away with it. Like I said, best case, it works great. Worst case, you picked up a good carb on the cheap that'll work on a bunch of different motors.

 

Haha ok. Didn't mean to get snippy..just been hearing a lot the past few days about different setups and differing opinions on the two far ends of the spectrum.

 

Don't waste too much time worrying about the right sized carb. Pretty much any vacuum secondary carb would be fine, it's only going to let as much air as the engine needs through. A 600 cfm Holley or Edelbrock is no problem.

As to which...you're getting into Republican or Democrat territory there. I like Edelbrock carbs, the one on my truck runs like a raped ape. They're definitely easier and more convenient to tune - a lot of the changes can be made with the carb still on the truck.

But if you can get a decent Holley 600 cfm with a kit for $60 go for it. Don't let the perfect be enemy of the good.

 

Quite good advice baron. I think I will take the 600..now..I know your an edelbrock fan..but would u have any idea what holley model carb would suit it too.? I guess they all deliver gas..so that's a start haha

 

This is what I was getting at. Sorry if I came off sounding a little edgy.

 

Nah..I never took it like that

 

Which Holley? I'm sure some are better than others, but a single fuel inlet and electric choke will make life easier.

Find a good ignition hot source for the choke - don't use the + lead on the coil. Dunno the stator output on your truck, it may not be enough to open an aftermarket choke all the way. I reckon you could use it to trigger a relay, though.

 

I know its harder..but my truck has a manual choke setup. I was lookin into the 570 cfm street avengers too.

 

An 1850 model is probably the most common and also the least expensive.

 

Are they pretty reliable?
