Quote: Can the problems of the 1407 be corrected or is it an insurmountable design flaw?
Depends on who you ask, but it seems to but an insurmountable design flaw
I wouldn't call it insurmountable ... assuming one doesn't mind spending hours and hours with a wideband , taking the carb on and off , drilling passages , etc ...
I wouldn't be surprised if by just changing the carb to something that is NOT a performer 750 wakes the car up?
The performer 440 intake is basically the same height as the stock iron and weighs probably 20 lbs less , the CH4B is about a 1/2" taller but should have no issue clearing the hood , the one problem with most aftermarket intakes is they think everyone is running dual feed side hung holleys and move the coil mount to the drivers side.
The best intake for an very close to stock look in the OLD Mopar M1 dual plane, it's a copy of the 1970 iron intake in alum.
