I have a friend that has a beautiful 59 chevy, and several times he's thought about going EFI with it, but he's more after the stock look so he's sticking with a carb, even though he is having nothing but problems with it. He's going to try a 409 carb on his 347 and see if that will help. We're going to throw my WideBand on it so he can try to dial in the carb better this spring.
