Projects What 2 barrel carb for 200ci I6

What 2 barrel carbs are best for a stock 200ci I6? Is there anything else I will need to change out for it. I have a stock 200ci I6 from a 71 Maverick in my 64 Ranchero.

 

Isn't the intake cast into the head on the 200? I've seen were the manifold was drilled for two more carbs for three single carbs.

 

Yeah I've seen that also, but id rather go with a 2 barrel if it's possible

 

I suppose it would depend upon the adapter you could find for it. A larger one barrel would probably be all a stock 200 could handle.
Weber makes a nice little two barrel, we put them on our air cooled VWs. If I remember correctly it had a primary and a secondary.?

Weber 32/36, on an adapter. Huge improvement, and not probably.

Measure the distance between the two studs that hold your 1-barrel on. I have a few spare adapters.

If I have one that fits, I will send it to you.

 

Come to think of it, I might have the carburetor, too. No promises, but I will check.

 

Definitely the Weber. A friend put one on his 1960 Falcon and it was a great improvement. So was replacing the 144 with a 200, and the Fordomatic with a C4.

 

With a adapter may be a 94 or 97 Stromberg.If you made a intake you could run two of them.

 

Great thank you! I will measure it tomorrow.

 

I am going to respectfully disagree on the use of a two-barrel through a two->one adapter. Have done a lot of testing to try to make this work, and never could improve on some of the single barrel carbs.

While using the Weber may be an improvement over the original single Autolite used as original equipment; so would many SINGLE Carters, or Holleys, or Strombergs, or Zeniths.

Depending on hood clearance, I would suggest looking at a somewhat larger single-barrel carb. Stromberg made a single-barrel with externally adjustable main metering jet, for the Chevy 235 that would be a good choice. You may have to machine the intake opening to match that of the carb. An even larger (if your engine can take it) single barrel with the adjustable main metering jet would be the Zenith type 228 used on G.M.C. 248 CID or even larger from a G.M.C. 270 CID. An issue here may be hood clearance, as all of these are maybe an inch and half taller than the Autolight; but then so would be the Weber with an adapter.

If you can find (or fabricate) an intake manifold/cylinder head that accepts a two-barrel, my choice of a two-barrel for that engine would be the Carter type WCD used by A.M.C. on their 196 CID 6.

Just my opinion.

This is the best conversion for the 200 L6:

This requires machining of the intake log, but as carbking said, the 2 into 1 adapter isn't the best design.
I looked into this carb when I had my Mustang, I sold it before I did any modifications.

Look up 1hotvega on flea bay. He modifies ford small six heads for two barrels. Does excellent work but pricey.

GB73,
Check out the tech section at Vintage Inlines.com there should be a chart with dyno numbers of the various carbs and adapters and how much it was worth.The small weber is Definetly a good choice.

 

I looked at the 1HotVega head, he machines them for an Autolite / Holley 2V which as opposed to the Weber is symmetrical fore and aft, while the Weber is a progressive carb.

But yes, expensive. As of this writing $1800, but it's a fully rebuilt head with porting and oversize exhaust valves, etc.

 

Have no idea what your objective is, like how much power you want and are willing to pay for. If lots of both, look into installing an Australian cross-flow head. Or find a 250 cid engine, (I think it is a "bolt-in", but not sure.)

 

It's not.

 

Same basic engine, with longer stroke, therefore a bit.taller, so maybe would hit hood. Also, bell housing bolt pattern (to engine) different, same as V8, maybe need different transmission.

 

It has a totally different water pump, too, which is larger and longer. It would put the fan well past the radiator.

It would require the radiator be moved forward, which is possible, or the firewall to be modified, which is also possible. Neither is easy, and neither involves bolts.

This ain't my first rodeo.

 

I have about that in my entire 200, and it makes 200hp.

 

Sorry it has taken me a while to get back to you. The distance between the studs is 3 inches. My single barrel has a leak around the throttle bushing area and I'm told by Napa that I can't get that in a rebuild kit. So I'm guessing I need a carb

 

No worries. Let me rummage through the adapter pile this weekend, and look for the wayward Weber.

 

Great thank you!

here is a volumetric efficiency calculator

 

Is that the distance on the inside of the studs, or center-to-center.

I found an adapter, but the center-to-center stud spacing is about 3-1/4".

I can mill the holes to slots, and put a little extra clearance in for nuts, if needed.

Still no sign of the carburetor that goes on it. I will keep digging.

 

That was the inside of the studs. I appreciate any help at all.

 

It looks like the adapter I have will fit.

I still cannot find the Weber. I have one more place to look.

They go for about $75 down here. I can probably find one.

 

Great thread with good info and a helping hand. So refreshing after the “who hates this or that” threads.

 

I have calls/emails out on two Weber 32/36 carburetors. I cannot find the one that I had.

They are $60, and $75 respectively. Hard to beat that price, with any of the other suggested solutions.
