Hi Tim
I'm I reading you correctly....you say from the "cowl to the back of the hood scoop is 3 1/2" So what kind of air gap do you have between the cowl and the back of the hood?? My car is not here so I can not measure from my cowl forward.

Thanks, Troy

....there is nothing like driving my 1968 Hemi Dart around town and having people looking at you like you're nuts!!
