[DeTomaso] Speed Demon 750 anyone?

If you do decide to buy a new carb, I'd second the suggestion to not buy an
"off the shelf" carb. I bought a fancy carb from one of the Pantera vendors
that was "tuned for a Pantera". But what is a Pantera? A bone-stock, 1974
engine with all the smog gear installed? A 1971 high compression engine? A
393 stroker? None of these engines will have the same needs, and a carb
tuned for one will work poorly on another.

The carb I bought worked horribly on my engine, which is far from stock.
After a lot of fiddling, I sent it to Chuck Nuytten, who does the same
thing Mike comments. There's a 5 page questionnaire about your motor, and
he tunes it and sets it up for your specific use. (It's also who milled the
choke off for better flow). I took it out of the box, put it on, and the
engine ran fantastic ever since.

Especially if your motor is a little different, I'd look at the option of a
carb configured for your specific engine instead of "one-size-fits-all"
