Hey guys,

The car is just about ready... very close to coming home from body and paint... after a year of customization over there I've hit my last and final problem. I will post pics when shes all done as I wont be giving her any justice if I post now...

I have seem to hit an issue with the scoop and air cleaner.

I have the stock and actual 1977 L48 hood on and purchases this scoop from unlimited:


Nice scoop looks bad arse from the front... the side looks ok... however I have added on top of the intake which is a new edlebrock performer rpm (some size as stock) there is a 2" tapered spacer

 and on top of that customized holly 4150 dominator bowl carb (750CFM)  thats custom jetted as well.

 (mines red Cool)

On top of the carb is the wonderful air cleaner....


Inside that air cleaner is this:


Here is a super poor diagram!


So the air cleaner at the highest point sticks out 3" through the hood. The scoop covered perfectly... however it just wouldn't function... lost 50% of visibility while driving and the fiberglass build up would be more costly than its disgusting look... plus not to mention a sports car is supposed to be smooth, not like a muscle camaro.. lol.

I think its time to start looking at nice looking vented hood where the cowl can be modified, or a super charging option thats beautifully cheap but introduces a slim hat... Any suggestions?

Thank-you guys and once again I apologize with my horribly portrait!

-Louis

P.S.
In case anyone is interested.... the current engine setup briefly is:

Original cast iron block (baked, cleaned, sand blasted, bored, honed and stroked to a 383. Aluminum assembled edlebrock performer RPM heads with racing valves (port and polished), edlebrock performance cam its a roller cam. Crank is the original crank just re-done, KB flat top racing pistons, performer rpm intake, 750CFM dominator 4150 custom carb, 2" tapered spacer... some other stuff (I believe compression is 10:1) "simulated" 600HP. THe trans is up in the air.. I have a 700R4, the dude who told me to use it actually is a douche and two other guys are telling me they can build a race trans out of a TH400 and or a TH350 for $1,800 and I'll be much happier.. which actually saves drivline cutting, crossmember changing, ect...

Any hood modifications will effect visibility, Louis. Our Sharks never had that good of a line-of-sight plan to start with....anything you add to it that raises the center area of the hood is just gonna exasperate that.
With that said, why not look into an L-88 style hood?

I did.. however its only a 2.25 inch gain... still not enough... its looking like I have to eliminate that spacer... but I don;t want to use that as an option... maybe I'm missing something...

Louis, what are your plans for driving habits? Is the spacer that important that you're needing to modify the body and/or buy another hood? I have a Barry Grant carb on top of a Performer air gap manifold with a drop base air cleaner and a 2" element on a healthy small block and it's an animal without a spacer. Granted, there's probably a couple of HP that the spacer would pick up, but....not sure it's worth the body mods...
 
Just food for thought. Good luck which ever way you decide to go...

How about using a shorter air filter to bring down the height?
K&N makes all sizes.
Or maybe that in combination with a shorter spacer?
I'm not an experienced mechanic, but it came to mind.
 
Keep us posted and we're lookin' forward to your pictures when you can post 'em.

Hey yall I finally paid the 15 bucks so I could come back and post. Here is what I was told by an old schooler. Taller plenum = Top end gain, shorter plenum = low end gain. Are you going to notice the spacer? probly not. I got the same issue which is why I'm going to the L-88 hood.

Hey guys....
I thought of those rectangular cleaners, but I'm not usre thye would allow maximum air flow. I know when that carb gets kicked on its gonna suck down air, but the volume that the air cleaner can allow at a given time may not be enough. Plus is that holley cotton gauze washable like the K and N?

The spacer I have to keep, it produces such good amounts of torque and HP for the price and keeping the fuel cooler is a huge plus!

Don't wanna supercharge right now, don't think I ever will, plus too much $$... any hood options?

L-88 baby, I'm getting one and I'm going to open it up on the from just like that scoop you got. If you do a google image search motion corvettes you can see some hoods done up like that. Basically the L-88 with a scoop glassed in.

use the 700r4, youll get a much deeper first gear (better off the line performance) and the drivability improvement with the overdrive.
