Air cleaner clearance issues

Hey there guys.

I swapped the Holley out with a summit racing 600 carburetor and am extremely happy with it. The issue is that it sits just a bout 1/8 inch higher than the Holley and my air cleaner will not fit well under the hood.
I am very reluctant in cutting the hood bracing, but if I have to I will.

My question is if you guys have an idea of how much is safe to shave off of the CI carb adaptor?
How thin can I go on the intake flange on the CI intake?
What is the best air cleaner solution for these set ups?
Ive seen a spectre low profile carb hat that would fit just barely right now, but I have read that it will choke out an engine at higher RPMs pretty bad.

Any ideas would be great!

Right now I have one of the high flow triangle air cleaners that I had to cut and modify to fit with the other carb.

Thanks guys!

I had the same issue with the triangle filter when I had my Holley 1940 installed. I had to trim maybe 1/4" off of the standoff flange on the bottom plate. This resolved my issues. Currently I'm running a 14" with a drop (don't remember how much) and a 2" element. This leaves me with plenty of room.

Forgot to mention that I'm currently running a direct-mount Autolite 2100 on a modified C9 log head instead of the 1940.

Hi, X2 look for a low profile air cleaner or check out the over the valve cover stuff on vintage inline. Good luck

here's the few I've collected for the "250-ina-bronk" or low hood issue:

1) Body Lift
2) Suspension Lift (yes, in some cases)
3) 'slot' the mount
4) remote a/c, carb hat, drop base ac housing, etc
5) hood scoop
6) late Maverick mounts
7) autolote 1100 / carter RBS carb, air horn-ectomy
8. mill head - direct mount.

So there's about 8 that work, some only for trucks & w/mine only a few of them.
Good Luck, if U can add to the list let us know!

some of the standard 14" element air filters with a "drop" base are actually lower then those triangle things...

Guys, make sure you use a K&N air filter so you don't richen WOT due to lack of air flow.

In low mount situation I cut the choke horn off to acheave better air flow into the carb

gotta get that post count up somehow, no?

So when you look at this picture, the hood has a dimple in the support to clear the factory aircleaner. That dimple land right ath the radius of the top of the carb. I had to bend the filer support down on that edge and cut the mesh to clear the hood. I saw the dual out carb hat from spectre that I could put a dent in on the shock tower side to help clear the hood. And I could just put the filters on each end and maybe fab a shroud for each so the header heat isnt completely killing the air.

What do you guys think?

Do U have 2 1/2 inches clearence?
Have U tried the "modeling clay squish"?
That would be the 'true test' of conditions…

I like the spectre idea as it may wrk
/AND/
get more air in there. Just can't tell if U have the room
(I got a 2nd & 3rd hood, 1 has a hole cut right where I need to guage it).

Good Luck, keep talkin.
