Anybody have experience with the Street Demon or Speed Demon Carbs? Trying to decide what one to put on a mild built 400.

 

Demons are said to be good, rumored to be the best. But I have no experience with them. I'm an edelbrock fan

 

. I usually just use the cheapest one of the size I want... usually from a swap meet...

 

I have a 750 Street Demon that is going on Dad's 400 - see the sig for details. Tim used it to dyno an engine and compared it to a Holley, IIRC. I'll see if I can find the results. But I do remember it did well in the test.

 

Here's the thread, and specifically the post in the thread where he gives the results of the 750 Holley vacuum secondary to the 750 SD.
