2.3 inch air filter enough?

E-3740 k&n element

I'm trying to put a base element combo together that will fit under my stock hood. I see the k&n 1.25 drop base says it won't clear elec choke but I fear the shorter base drop won't be enough.

I've read a ton of threads and can't solve it.

If I get 5/8 drop base and 2.313 element will this clear elec choke and stock hood? It's going on performer rpm and demon 650.

Re: 2.3 inch air filter enough?

Nobody? Surely, there has to be some combos that people are currently running that work. With so many air cleaner and element choices I don't want to guess and I don't have an air cleaner to smash clay on under the stock hood to measure.

If you have a Performer RPM and Speed Demon on a stock 350, with a stock hood I would like to know your air cleaner assemblies. Thanks.

Wink Re: 2.3 inch air filter enough?

Use of a given air filter, under a given hood, with a given engine, on given engine stand(s) with given mounts, is a variable.
Throw in your intake, carb and install combo and the dimensions change again.
What work(s/ed) for one person will not usually work for another - unless it happens (luckily) to stay under their requirement minimums ...

So the only real way to determine a given set-up is to measure, calculate, re-measure and then order/fabricate the necessary parts.
I have found many different measurements when I have done this same exercise ...

Having the air cleaner lid to close to the carb intake can really effect (kill) air flow and performance.

Original L48, engine mounts and SS hood. I removed the hood insulation yesterday to give a bit more space.
Okay so if I need the 3 inch filter, I guess I need a deeper drop base. Do you know of a drop base that will fit a new Speed Demon 650 with VS and elec choke? I saw that Demon makes an air cleaner with a .5 drop but I don't think that will be enough. I looked at two K&N drop bases but the note on specs says it won't clear a elec choke (Now it doesn't say if that's a choke on an Edel carb or not)

Also, what if I did the extreme cover? Would that work with the shorter element?

Re: 2.3 inch air filter enough?

Oh wait a minute! I was thinking you were running a BBC. It's a SBC. You might have room for even the taller element. Do this: put something on and close the hood. Slowly, very slowly. Then go from there.

Put it on a fuel bowl? I don't have an air cleaner to test on it.

Re: 2.3 inch air filter enough?

I posted in your other similar thread I use a non-drop base air cleaner and K&N Xstreme top with a 2" filter on a 68 with a SB and the same intake and carb. It works well IMO. I tried it by putting a cone of clay on top of the lid and closed slowly as Fred said. I had about 1/2" of clearance. You could do the same on your carb or find some air cleaner base or 2X4 as a platform at least to test it with so you can get a measurement with the hood closed.
