Thinking of buying a Street Demon Carb...

I've got a Street Demon 750 w/polymer bowl on my 440. I'm not a tuning god like some of these guys, but have had zero problems with mine with hardly any changes out of the box. I used the Demon Air cleaner with a edelbrock Performer intake. Lokar throttle cable and kick down. No clearance issues.

I think Demon had some production issues with quality initially, but I think it's behind then since Holley acquired it. Could be wrong though. Price is right though and Summit is great on returns.
