I have had two Speed Demon carb and they (BG) have very poor quality control. Both of my carbs where full of metal shavings from the CNC process on the metering plate. One of the jets was cross threaded and striped. THROW THE CARB AWAY! I changed from my speed demon to a Holley 650 dp classic ($325.00) and picked up .15 in the 1/8 mile and the car drives incredible. Barry Grant is the biggest joke (ripoff) placed on the hotrodding public. Piss on BARRY GRANT. Just my opinion.
