Before I make a foolish mistake
I have a 1960 F-100 with the 223 in it.. has anyone tryed the 2bbl conversion on one of thies, and does it help any with it at all? Ie more power, better milage? Or is it a waste of time?

Not a student of the 223, but let me guess: It's a 4 or 5 mainbolt motor?
It's 45 years old?
It revs to about 3000 rpm now?
More carb is going to make it want more revs. Given that you are the owner, do you want it spinning more revs?
Got your answer?
Check out the engine swap section. Maybe a 300 or 302 swap for you?

Guess it's time to scrap the 300 and go retro. (mine starts to shake pretty good at 3300) Unless you can get a full on two bbl manifold, you will be stuffing the two bbl intake down the same small hole as the 1bbl. Marginal improvement, I would think.
The Clifford folks sell the 2 or 4v manifolds:

If you can spin that thing to 6K then you will greatly benefit from the 2v or small 4v.
Happy Motoring!
