clearance pictures.. something cant be right??


see how close it is. and this is a 1 inch filter. it is a drop base but idk what size. i can meassure it ill do that in a min. but as you can see the top plate is above the master cylinder, it is very close on the hood and i still have to ad a 1/2 inch spacer under the carb and idk how im going to be able to do that with how high it is sitting right now...
any and all help will be appreciated.

What intake is that? You are not going to be able to use any spacers with that carb and stock hood. You will need a 1/3/8 or so drop filter assembly with a 3 inch filter. That 1 inch wont feed my lawn tractor.

i put poly motor mounts in so that might be part of the problem but it is sticking up awefully awefully high. i have a holley street dominator intake manifold, and the carb is a 650 double pumper the choke tower is milled off. i know there are people on here running this intake can some of yall help me out?
mw66nova has this same intake and carb and he fit it under his stock hood but he couldnt tell me what size base air cleaner he had...? im lost i would like to hear some opinions on what to do whether it is switch to another intake or different motor mounts but i need to do something to lower it down some with out loosing any performance.
the 1 inch is really my only option so you guys laugh ya but i have no other choice, im planning on getting one of those breather lids though so that should help alot only things is its going to be so close to the hood idk how much it will help.

Right now your only option, as I see it, is to buy a cowl hood. Plain and simple. If you are using nitrous, that 1" (even with a breathable top) is NOT going to give the motor what it needs. That is like sticking a popsicle in your mouth, plugging your nose and trying to breathe. Not going to happen.

i don't think a nitrous plates and a rpm type intake and the carb on top with air cleaner would all fit, it "might" with the L88 corvette filter possibly, but that's about it. Removing the inner structure off the hood will net you another 3/16" of clearance where the air cleaner should go.

i have looked into that but i would rather find something else i mean i could get a better lower profile intake for less than that air cleaner but it would look very sweet on my car, i just dont know if it would help as much as i need it to help and thats a big price if it isnt enough you know?
we have a 71 corvette and i threw that base on my car and it did pretty well i could run the three inch and it was close on the hood, but idk if i could run the spacer and that base/cleaner. ill measure the base here in a min. and post up how big the drop base is.
does anyone know of an affordable shorter intake that still makes pretter good power? ill have to look around summit later on tonight i havent had much time. lately.
i appreciate your comments and suggestions guys i need to get this figured out and i figure someone with real world experience will help me a ton.

well i looked on summits site for a little while. it looks like weiand has a stealth intake and a single plane intake that are both low profile, holley has the same intake as what i have right now in a low rise version so i will have to check those out.
anyone here have a rpm-air gap? can someone measure the height of it? this is the intake i wanted to get at first but decided to go with this one instead b/c of the price.
any more suggestions/comments to help me out? the rest of my nitrous parts come in this week and i would like to wire it all in by christmas, but i need to figure this problem out first.

There are basically two drop base 14" air cleaners out there... actually 2 bases. All the mfg's use the same stuff, and stamp their own logo in the lids basically.
Theres one thats a 5/8" drop, which it appears you have, and one that has a 1-1/4" drop, which is what you need. Only the bases are different. You can tell them apart by the 'throat' of the base (where it mates to the carb body)... the 1-1/4" drop base will have a shorter 'throat' and the 5/8" drop will have a taller one.

did u even cut out the bracing under the hood where the air cleaner sits to see if that helps? you can also shim the back of the hood up a little bit and not have it be noticeable to get more clearance if/as needed.

i have an iroc hood.. i dont think there is any bracing in the middle b/c of the louvers. and i dont want to shim it, it lines up pretty good right now. i think i will try the 1 and 1/4 inch drop base and see how that does.

go pop your hood and look at the bracing there, cuz it's there, I cut out my iroc hood before. like i said it's worth 3/16" if you read my posts above. Otherwise try the other air cleaner and if it's close then use my ideas.

mmm...I have an RPM intake, holley 650 double pumper, 1/2 spacer, and a holley open element assembly with a 3" K&N, and its a very tight fit. if i snug the wing nut down really tight, the hood closes perfectly.
i had to waste 30 bucks on the holley assembly, because it had more "throat" to clear the float nuts, but i don't think it had more of a drop base than the edelbrock open element.

I have a dual feed Holley, RPM Air Gap intake, and the 1-1/4" drop base. Its fits under the stock fibreglass Z28 hood... doesn't clear by much, but it does fit w/o and cutting of the hood. Looks like it would have a bit more clearance under your hood than mine, as I have the two molded-in 'scoops' that reduce clearance by 1/2" or so.
