Troy:

I have:

-Edelbrock Performer RPM
- quick fuel HR-680-VS (4150 style)
- 1/2 inch spacer
-K&N 7/8 inch drop base 85-3545
- K&N 14 x 2 5/16 element E-3740
-K&N Xtream top 66-1401XP

If 12:00 on the air cleaner is toward the radiator, then the closest point between air cleaner and hood underside is at 2:00 (due to the engine being offset 1 inch from the centerline of the car. At that point, I have between .250 and .375 inches of clearance.
