Demon Carburetors recently released an advertisement suggesting you can install a new Street Demon carburetor and have your car running properly within 30 minutes. We decided to take that challenge, and installed a Street Demon onto V8TV fabricator John Moss's 1972 Chevy Nova. The car is powered by a 383 stroker and was suffering from temperamental carburetor issues. The Street Demon is an all new design that features several innovations including a leakproof main body, 625 CFM airflow rating, small primaries with a large goggle valve vacuum secondary, and minimal adjustment requirements. Watch the video to see if John was able to not only install the Street Demon in the 30 minute window, but to see what a difference this carburetor made on his Nova!
