Thinking of getting one when I do my carb (TPI now) swap. Thinking of getting the speed demon 750 cfm, vacume secondaries. The engine is a 350, but will eventually be doing a 383 buildup. So what do you think? Thanks.

 

I run that carb on a modified 400. It might be a little big for you depending on cam and rpm. They flow a lot more than their rating. I wish they would rate them at actual flow. I Had to work on the idle circuit, choke and jetting.

Oh yeah, once I got it dialed it it's killer and my wife even went whoooo when she say it. Count on buying the fuel inlet set up and choke.

 

I love my demon,i recommend it.Easier to tune than a holley and actually improves the way my car runs.I run the 750 mechanical secondaries on my 355,but that is with a 4 speed.
