So I haven't put the hood on yet so I don't know for sure, but it sure looks like I'm going to have air cleaner clearance issues.  My plan was to use my OEM '76 base and snorkel assemblies with a '73-'75 top (which I already have) so I'd have a quasi-open element in addition to cold air from the snorkel.  But, I think the metal part of the snorkel that's attached to the base is going to hit the hood.  The Vortec intake I'm using is only 'bout an inch taller than the stock so I didn't think I'd have problems, but it just doesn't look right.  

Assuming I'm correct about the clearance issue, I think the plan is to go to a true open element assembly, possibly with a shorter K&N element than my current 3.5".  I'd like to still use the '73-'75 top because it's brand new and I like the looks of it - problem is it's 12" and all the aftermarket stuff is 14".   Anyone know where I can get a drop base air cleaner (all I need is the bottom plate) for a 12" dia. element???  Other idears?

Looks awesome!  A little more than I want to spend, but it would be a lot less than a L88 or Stinger hood.  I'm actually thinking about using my OEM ass'y as a base - just going to take a little work with a jig saw.  I'll cut it a little smaller than the filter element so the ugly edge won't show.  But....I hate to cut into the original ass'y.  Going to think about it a bit....

I saw one of those on a vette, an early c-3, last year a Eureka Springs. I thought it looked exotic, cool too...lol  Didn't know they cost that much tho. Do you know how much more hood clearance they give? I have a 2"x14" now with only about 1/2" clearance with just an Edelbrock Performer

Yeah, I'm wondering about the added clearance, too since most of that unit's height is on the sides, possibly beyond the bubble part of the hood.  But it probably adds at least some clearance.  

Longhorn, glad to know about your clearance situation.  My original plan was to go with regular heads and a performer intake and there was a time when I had both manifolds, along with the stock one and measured them all together.  If I remember right the ebrock and the vortec had very similar heights (approx. 1" higher than stock) so your situation should translate about the same to mine.  My plan is to use a 12" dia, 2 1/2" element so I should be very close, but OK.  I hope....Smile

I'm really not sure of the clearence with a stock hood. I have an Edelbrock fuel injected ZZ4 engine with vortec Edelbrock heads (RPM E-Tec 170) The throttle body (1000 CFM) sits on top of a Edelbrock RPM Airgap manifold. I had to go with an ACI high rise hood to accomodate the extra height of everything. The hood is larger on the sides to accomadate the air fiters. here is the hood that worked for me...........

The Penguin (Spielman5) has one of those on his '76. Looks neat, and give more clearance. His car also has an aftermarket hood that is prolly a foot taller than stock, so he prolly really dint need the extra room.

 I've thought about going with an early LT1 hood so I could keep the wiper door and get a little more clearance for maybe at least an RPM intake but I've gotten the impression that those hoods don't really give you much more room and I really don't like the big rise in the other hoods. Maybe someone makes a little short carb? LOL Or... I could blow some big bucks on fuel injection! Gotta recover from this latest reeming first tho...Angry
