im at the assembly point with my small block 302 cobra build
what I am wondering is
I just scored a really great deal on a edelbrock dual quad air gap intake and 500cfm edelbrock carbs, problem im having is the edelbrock air cleaner is too tall to fit under the hood of my cobra and im wondering what others have used for air cleaners on a dual quad edelbrock intake?

please post pics

Is that an Edelbrock #1235 air cleaner? Accessories - Pro-Flo Series Round Air Cleaners - Edelbrock, LLC.

If so, it's spec'd as 3.5" tall. The question when looking for a replacement is this: Exactly how much too tall is it? If it's over 1" too tall you may need to look at a taller hood scoop, drop the engine, etc. As LMH pointed out, you may be able to go to a pair of smaller filters, but 6.5" units may be too big, as that Edelbrock page seems to indicate centre-to-centre carb spacing is 6 7/16".

The trouble with dual quads is you can't run a drop base type aircleaner since they are so close to each other.

A custom enclosure with a pair of ducts to a pair or pod type air filters would work. Not as pretty though.

A pair of 6 x 2 K&N filters might be enough.

My solution was to replace the 3" tall K&N air filter that came on my aircleaner with one about 2"-2 1/4" tall and to use the "FilterCharger" top with the cleaner element in it. K&N has a search function that can be programmed for filter diameter and height and then you just use the filter that it specs...mine turned out to be a stock filter for a Toyota Camry. I used children's play clay to measure the clearance to the underside of my hood scoop (my 10" diameter K&N system fits up into the hood scoop) and it turned out I had 1/4" clearance. I have not had any clearance issues.

I would, however, like to use a different intake manifold with a bit more height. In order to do that I'd need to go lower with the engine, which would introduce "phasing" issues with the driveshaft angle (having a 4-bar parallel rear suspension, I suppose I could tune all that out, though). I have heard on the Ford Mustang forums that the 5.0 Mustang GT convertibles used motor and transmission mounts that relocate the engine about 3/4" lower than the hardtop models. I cannot verify this, but a trip to a local Ford dealer for a comparison of the two motor mounts might prove it to be true.

Cheers!
