Thermo plastic body is the way to go!
That's a plastic body? Post carb #s please. Who makes this?
Looks like a Street Demon?
Are the throat size and spacing the same allowing for the same air cleaner
I bought 2 of these when they were $200 each and free shipping. I took mine apart and found nothing wrong. More like operator error. Poly body is 1901.

$200 each!? Holy crap! If these things work well these could be the hot ticket for our engines. Thermoplastic body, good price, seems like a good setup!
I like those Demons. If I had seen them first, I may not, have purchased the 2 Edelbrock.s 
My engine guy used a set of those Demons on a 625 hp stroker and he said they worked great.
The jetting was perfect right out of the box and the throttle response was really good.
Lamar Walden tested a set when they first came out. They made more power than similar Edelbrocks.
I'm not sure if the Edelbrock carbs they tested were tuned or not so your results may vary but it could well be that these carbs are better suited to these W motors.

Out of the box on the chassis dyno, mine was improved enough to justify the purchase. Not just the peak power but pretty flat lines all the way up. Just happened to catch the Holley sale on Ebay. Sniffer up the tailpipes says they are good to go. I run an Offenhauser 360 2x4, maybe that helps with distribution, maybe not. May buy an Edelbrock 2x4 just for testing again next winter.
Most of the Nostalgia Super/Stock rules call for AFB or Edelbrock carbs for racing on 409's.
Exactly. For county road racing events, these should work just fine.
