hello guys,
just picked up a 2151 performer intake for the 67 Cutlass, and it says this
intake will not work with out mods to the hood (cutting hole) anyone know of
what will work so that I don't need to be cutting up my hood?
thanks for any help

sorry guys, the part number in the header is wrong 2151 is what it should be

I'd measure the height of you current set up and compare it to your new sit up. you may get by with a lower air cleaner base like the ones on a corvette and a thin air cleaner. if that's to high the only simple alternative is to get a different intake that will fit your application. Research is key.

Isn't a performer almost the same height as the stock intake??

You do know the 2151 is for a BBO and not a 330, right?

In any case, be aware that a thin or low-profile air cleaner that is overly restrictive on flow will negate the performance increase of an aftermarket intake. Engine performance depends on TOTAL airflow in and out of the engine. Using an overly restrictive air cleaner assembly is like sticking a finger in your nose. Same goes for an overly restrictive exhaust.

yup, this Cutlass has a 400E and has the stock intake.. the only reason to go with the 2151, weight... and for some reason I was thinking that it was about the same height as
the stock intake... the intake is on its way to me now.. I down loaded the install from Edelbrock and that's when I saw the side note, I know it would not work on the Tornado but right next to that, 64 to 67 Cutlass with out doing mods to the hood.. but seems to me somewhere there is a simple fix, with out chocking off air flow.. a simple 1 inch drop air cleaner bottom... but I don't remember

You can take the hood off......that way you won't need to cut it😉 .....sorry, I couldn't resist!

A drop base air cleaner will NOT have the same airflow capability as a regular one. The drop base air cleaner puts the underside of the lid closer to the carb air horn. This results in a smaller annular area and thus less airflow. By the way, note that the carb in this photo doesn't have a choke. Imagine how much worse this gets when there's a choke housing sticking up from the air horn.

like this one ;-)

Why are all of these guys posting on this thread when even the resident expert can't answer the question.Will it work with a drop air cleaner or not.If my hood wasn't already modified for racing i might be able to answer this question but i am using a torker intake.I find this strange that no one has a answer.{ Yes,no,or a drop base restricts air flow to the extinct that it is better to use stock intake}

olds330

Joe, that's a little exstream, I do understand what you are saying.. but I don't think there is that much clearance problem.. the upside, living in Tampa, I don't run with chokes

wr1970

Good picture Joe but not a good answer.Why you are not telling what the distance is to the hood when using a drop base. Is that a one inch or a two inch example?Maybe you don't even need a drop base?Your theory is sound but not correct unless the answer is clear.

joe_padavano

I have no personal experience with a 2151 on anything. My only point is that people often spend a ton of money on "hot rod" parts, then handicap them to make them work, with the result being no performance improvement. Getting the most from your car requires a total systems approach - all parts of the system need to be matched. For example, it makes no sense to install a larger Holley with a restrictive adapter plate, yet lots of people do it. A 1" drop base air cleaner has 1" LESS clearance from the underside of the lid to the top of the air horn. That means that flow is less, period. Is it good enough? I don't know. You'll have to do your own research. And unless you've machined the choke mounting box off the top of the air horn, the restriction is still there whether you use the choke or not.

wr1970

Now that was a good answer you don't really know. And that is the honest answer.I can tell from experience that a performer intake is better than stock intake on a 1970 with a stock hood.I just don't have a answer for a 1967 and you did give sound advice Joe.

ent72olds

Why are all these guys posting without an answer? Good question.....I guess you can add yourself to that list..... Don't forget, this is an open forum discussion.

wr1970

I will also say they make drop base air boxes for ram air systems also.

wr1970

Go away!

ent72olds

Huh?

wr1970

What you didn't understand i race a 1967 and a 1970 olds you do what is your stock car stock intake. We are debating if it really matter to the amount of air on a drop base or not.I think it should work as my 67 is right at the bottom of the hood with a three inch filter and a torker is taller than a performer.

wr1970

Joe my air base is flat not drop also.

oldcutlass

Time out, if the op is using a Quadrajet or a Holley, The L88 style aircleaner should work. Will it restrict a bit of airflow, probably, but GM used it for many years to shoehorn a BB under a flat hood.

wr1970

I agree Eric.The point i was making was the stock air cleaner is a restrictive airflow from the factory. The element isn't as tall as what i am using.At two inches not using a stock air cleaner can this would be getting more air.See example that 330 posted.

oldcutlass

Considering a stock air cleaner draws air through a little snout, yeah I'll call it restrictive.

wr1970

Joe P i meant no disrespect you were showing good info and sound advice when using a stock type air cleaner can. If you feel that i did please accept my apology.

ent72olds

No, I understood everything just fine... I made a joke to the OP. You jumped in flaming everyone who had replied to the question made by the OP, that couldn't give a definitive answer. Where I did start losing "my understanding", was when you replied to my comment about you adding to the "non-definitive" answers, which I did with a wink, leading to you respond, "go away". Where I really went into the weeds was reading your above ⬆️ post.....without punctuation comma I can't make heads or tails of it period
Anyway, sorry to the OP for getting off topic.

wr1970

Whatever.

Sucks Rocks when people rip your posts apart and don't offer anything constructive doesn't it!

wr1970

What is your point? Do we have two wise guys with no real info? Joe P had info i felt that he didn't have the ideal of the question correctly.Being as i thought there was no problem by knowing how mine looked because i have a 67 i reasoned it should fit fine with a drop base or a set up that the op posted.Which by the way is what i am using. I guess Eric agreed in the end using the factory setup wasn't a good ideal also.cjsdad did you not see the post i made on your thread about eating crow? Have a good evening.
