post pictures of your cowl hood A-Bodies. which one would be faster and more effective a Cowl hood or Aero hood scoop? Any track back to back testing.

I've done a bit of research on this lately. Big aero scoops seem to be worth a little bit of ET over cowl's or other small forward facing scoops like you have now. The con is they're a pain to see around, if you've ever driven a car with one, you know what I mean.

My car hates the cowl hood I run a 5inch glasstek similar to Johns.I have tried 3 to 4 air pans,blocking this and that and different carb spacers and it dirty's the plugs after one run. I also run a max effort carb that's 2.20 bore that's made for the most air you can throw at it.

Chris how does Butch Kemp run so quick with a cowl hood on the Mustang and its sealed to the hood
You need to look at the distance from the windshield.. close(about 1" to max 2")... this is mine but its no A-body... I set this up up so I could hinge it but I am thinking about making a slider on the back opening to get it close for racing

Mine loves the cowl hood(6" glasstech)...no air pan or even close to the windshield...145mph in the 1/8 and should be in the 150mph range with the new combo !!

Another thing to think about... when you are traveling down the road in a rain... which way do the rain drops go... if up then its not gonna put air into the back of the cowl... the cowl itself is blocking the upward flow if its close enough to give the low pressure area needed at the back of it... so between the low pressure created from the intake/pistons and the cowl close enough it should get good flow.... I was gonna do a test on my car(P-Body) and a guy that was running a cowl.. we both had similar speeds but he blew up the engine and I never got the chance

Carbs are pretty much center of scoop and the front carb is about 3 inches from scoop, rear carb a little more clearance. There is about an inch and half clearance to windshield and carbs are not sealed to hood.

On another note. SS/AH do they seal their carbs or not to the scoop?

So does it run quicker sealed to the hood or not sealed?
I had a smaller cowl hood with a single carb and sealed it to hood and didn't make a bit of difference, now with the tunnel ram and two 4's i didn't mess with trying to seal the carbs on this hood.

FWIW...I used to run a six pack hood on my cuda. It ran about a tenth quicker and 1 mph faster sealed than it did unsealed. I switched to a 5" cowl hood, unsealed, and it ran the same as the sealed six pack hood. This was on a combo that I'd run for years. I have experimented w/ sealing the cowl hood to the carb but haven't seen anything really.

If you go down to the US Nationals and look at all the hemi cars, not one of them that I saw had there hoods sealed to the carbs.

Using drop bases on the carbs will fix that. Seen it done many times. If it was worth any power on those cars, I'm sure they would be doing it.

If you`re talking about the Hemi guys, I read somewhere that they can`t use air pans.................
Sure they can, problem is they don't help. The scoop has to be kept within factory dimensions and as discussed in other threads is not high enough to do any good. Sealing the scoop would probably cost it air vs letting it get some underhood air unsealed.

Hi Monte in your opinion is there an advantage in the glasstek 5" six pack scoop over the glasstek 6" cowl hood thanks for any insight you may have

... they just arent tall enough to get up into the real air flow... they MAY be getting a good percentage of their air flow from inside the hood area.. I picked up ET and 3 MPH on my scoop when I sealed it

I would venture a guess that this car will run the SAME, with or without a plug in the scoop
