Re: Speed Demon 750cfm carb
Goodlookin, This carb will fit any manifold with a 4150 flange. What kind of engine do you have in your mustang? I had this on my 383 with a healthy cam and it fed it no problem. The jetting was relatively average.
Bream- I have no idea about CA they are in their own world.

Re: Speed Demon 750cfm carb
That is some decent lift!
I ran the comp cams XR288HR, specs were
236in 242 ex @.050
.555 lift in .576 lift ex. with a 1.6 rocker
110* LSA.
Idled around 800rpm
The carb had no problem feeding it. Sorry I can't be much help other than that.

Re: Speed Demon 750cfm carb
Brent;
I have a freind who may be interested, would you ship it for $300 to Canada? To Ottawa Ontario K1B 4P3.
It would HAVE to be through USPS if you do, not UPS. Requires you to fill out a form. Please let me know.
