Not sure what difference in carb mounting flange height there is between the M1 4150 and 4500 intakes. The M1s still look lower to me than a Victor, and definitely lower than an Indy.

IIRC some 4500 carbs are taller than 4150s, and there can be differences in available drops for air cleaners that fit one or the other. More than one variable to take into account...
