i don't beleive this...........every body worries about there intakes/carbs not fitting (including me) but the reality is very few of us have problems....do you due diligence but don't be surprised if others have no problems especially when they use drop base air filters

I'm not a vegas gambler type but I would bet money it willgo under your hood with a good drop base air cleaner I looked
up the height specs in my catalog it is just barely any taller
then the other performer manifolds.

# Action +Plus Intake Manifold1996-Up w/Vortec (L31) heads
# Idle-5500 RPM
# Height: 3.375" front/4.5" rear
# Port size: 2" tall/1.06" wide
# Square flange carb mounting
925-8121
Here is a link http://www.holley.com/8121.asp
Of course if you want to run a qjet this will probably not help.
FYI: I have an edelbrock EPS which has a A-3.75 B-4.80 height. I'm running a 1 1/4 drop base and a 2.8 inch tall air cleaner...under a stock 72 hood.
The edelbrock specs are (as you know)
A-3.87", B-5.28"
