    I'm gonna ditch the air cleaner box on my 84 and go to an open element. Anyone know what open element K&N will fit? It's a debate between the 9 /16th raised element, or the flat offset base for HEI. I'd figure the raised one would clear fine, right? I'm just confused if I NEED to have the flat based one in order for it to fit my truck, since I have HEI.

    I'm running a 14x4" open element. Mines a carborated motor ('79 model).

    It's not the flat part that makes it clear the HEI. It's the offset hole for the carb that makes it clear the HEI. It pushes the breather forward to clear the distributor.

    What kind of shape is your airbox in. My cousing just bought an old K5 and needs a descent airbox, I may be willing to buy it off ya to offset the cost of the K&N.

    If you didn't built it yourself, how can you call it yours.......?

    It depends on where your coil is mounted. If you have the HEI setup with the coil in the top of the distributor cap, then you need the offset housing. If you have the HEI setup with the coil mounted on the intake manifold, then the other one should fit. I'm not sure what year they changed from the integral coil to the standalone coil.

    I haven't really taken a good look at the airbox. I haven't seen any really bad dings or anything off of it. It's ready for AIR, so it has a hole in the snorkel to accept a heat riser, or whatever the heck comes from the manifold to the snorkel. I'm getting the truck back today (hopefully). I'll fill you in on the condition later.

    I was able to fit a 5" tall K&N with no offset. They called it the dropbase version in summit catalog, but it was barely dropbased. I compared it to a friend's dropbase and his really has the base dropped. I have the HEI dist. with integrated coil. It cleared it fine. The only problem is that the wingnut has to be tightened well, or it will (barely) scratch the hood.

    Good luck

    I was looking in the summit catalog, and they have gauze/oiled reusable open elements for about 3/4 the cost of a K&N version. Anyone heard anything about these?

    I have a flat bottom non-offset on mine. It fits fine w/ HEI. I don't know why you would need the offset.
