Please don't believe them. It's all marketinig hype. Most people buy based on size and 400-500 CFM carburetors just don't sell. Go look up the SAE standard quoted a few posts ago. The engine size, the cam, none of that is part of the standard.

What does make the Autolite almost unique and what does make it perofrm better that most other carburetors is its anular fuel discharge in the booster venturi. The anular discharge atomizes the fuel much better which gives a better fuel distribution and allows the fuel to burn more completely for less emissions problems and more power. The 4100 line is also easy to work on and doesn't leak like the Holley and Quadrajets.

I have no idea why Ford/Autolite stopped using this design but Holley uses it in the 4010 line. In any case you might like to see the results of the following:

Today I talked to a local speed shop, Steve Alsworth's in Fuquay -Varina, NC and they will flow test three carburetors for $100. I'm going to have them test my one small 4100, a large one and one I've modified by taking the lip out of the venturi with small files and sand paper.

They're backlogged so it may be a few weeks. Send your e-mail address to me if you want and I'll keep you posted. In any case I'll put the results here when I get them.
This thread, so far...
