Gregg Babbit – :
Working great! Basically plug and play from stock
Eric D. – :
This carburetor is awesome on the basically stock 396 in my 70 Chevelle. Used it to replace a carb custom built by one of the more popular online shops that specializes in Q-Jet carbs, which ran like garbage. This Jet Performance carb was better in every way (and less expensive).
JET Performance – :
Hey Eric, thank you for the share and continued support. Enjoy the carb and Keep Wrenching.
