Thinking of buying a Street Demon Carb...

Demons had issues with junk in the meter blocks....about 6 or 8 years ago!
My speed demon works great on my 410.

Funny how people keep a horror story going so long...
If you want to know what a real waste of money is, buy an avenger Holley and put onto a mill with some camshaft, lean pile of ****. They work 'ok' on stock cam motors.
