Carb question

ramman7284, you don't say what your running for a transmition or if your car's a 4 speed but Demon carb has been bought out by holley and their new line "street demon" carb is def making some impact. 625 cfm may be what you looking for in a vacuum secondary automatic tranny.

Very innovative. I have the 625cfm polymer on my 360/300 crate with a 727, vacuum secondary. Car goes like a raped ape. Very easy to set up with a vacuum gage, and flapper adjustment easy as pie.
