Been using a 14 inch edlebrock with a 3 inch K&N filter. I just added a 3/8 insulator under the carb and now there's two probs: First and foremost the filter hits the hood.
Secondly the bottom of the filter assembly now its the HEI plug wires and it hits hard enough where I know it will slice a hole thru two of these new expensive Taylor wires and arc out.
I sliced open a 3/8 inch PCV hose and put it along bottom of the chrome filter, by the wires. But then the filter won't go on the carb - that's how tight it is. I can get it on there if I dont protect the wires but I know it's too tight to drive it like that. (even IF the TOP didn't hit the hood)
I don't know if this is relevant or not, but I had to use a 13 x 2.5 element... had a hard time finding one... NAPA #FIL-2102. Just picked up 2 replacements today. Base is drop base.

See attached images ... wire loom won't fix interferance.
First is the old drop base, sitting on top of the ol' K&N filter element
Next is an overview of the engine
Next is my underhood insulation with a new hole in it from carb stud
last you will see the interference between the base and the distributor
If it were mine, I would make an offset air cleaner from the parts you already have. First check to see how much hood clearance you have at the front of your air cleaner with clay to determine if an offset will work. Cut the center of the base out around flat area by the carb opening. Shift the base forward until there is clearance for the distributor and mark the new location and clamp the pieces together. It's best to weld the pieces back together and metal finish them, but if you don't have access to a welder, you could screw and glue the pieces together with the screw heads underneath the base. There will be a gap where you shifted the 2 parts that you'll need fill with another piece of scrap sheet metal. To make the lid fit, you'll need to heat and bend the air cleaner stud to allow for the shift. If you don't weld all of this, you should seal the edges. You mentioned the stud hits the hood, you can try a Mr Gasket flat chrome lid, which will allow you to shorten the stud quite a bit. Before you close the hood check for clearance at the front and center with clay.
I use a bolt with a tapered flat head that has an allen head on top instead of a carb stud. This fits flat on top of the lid when tight. Email and I may can send pics. If this isn't too much of a "Bubba" fix you could clearance the back edge of your pan edge. It shouldn't require much material removal and would eliminate any sharp edges.
[QUOTE=Yellow73SB]Hmm ive never seen them that fit holley demon crbs and I have pretty much every circle track magazine and been to many NASCAR surplus shops.
How are they going to offset the air filer if the carb barely fits in the drop now?
This is mine. I have no top and I cut the bottom down at an angle. The hood seals the filter. Notice how the carb barely fits.

Don't really see how the carb fits, I know what you're thinking but they are around. They may not be offset the full 1-1/2" but they are made, Summit has a Moroso one that may work. Also why didn't you just buy one or at least do a little better fab job with yours? Pretty nice car to start bubbafying-course that's just my opinion.

I can't figure out how to smooth it out with out using anything that could go into the engine.
