I've done some searching on the board, and found lots of info on the shaker hood on a 3rd gen. Here's what i have so far:

3rd gen T/A's have a low intake to hood clearance

I need to get the scoop from a 77-81 T/A, and make it functional

this scoop WILL clamp on to my stock air cleaner housing


that's what I gathered. what i need to know is these:

the T/A hood slopes down, the old ones were flat. do i need to tilt the shaker, or install it flat to duplicate the right effect?

I'm running a performer RPM intake. will the shaker set-up work with my car?

any other tid bits of info would be great. I'm bidding on scoops on ebay, and I kinda need to know soon if this isn't feasible with my intake. I know some of you guys have done this. is it worth the hassle? it looks awesome, and provides a great alternative to the minimal hood choices we have for our cars. thanks in advance for the help, guys.

IMO, the 3rdgen Firebird hoods are level enough near the back (where the carb is) that it would look right. I'd just install it 'flat' on the carb.

The intake manifold won't make any difference, except maybe how high it will sit. The shaker sits on your carb, not your intake manifold.

flyitlikustolit

that's what I'm worried about. I'm afriad there may not be enough clearance to allow the shaker to sit.... which will mean I'm stuck with a scoop i can't use. any other info?

Air_Adam

what do you mean 'not enough clearance'? Its basically just an air cleaner lid, isn't it?

I could be wrong but i thik you would need the lower air cleaner assembly too, it's been awhile since i worked on or saw a second gen T/A but i thik the whole air cleaner assemblly is shaped almost like a turbo 350 tranny pan

Gumby

clearance should not be a problem. lots of room.

flyitlikustolit

ok. one last check before i bid: I should get the 77-81 shaker, and lower air cleaner assembly, and remove my 1" carb spacer..... and the whole shaker assembly will fit on my carb, on top of my performer RPM intake?

87and 93birds

i am in the process of doing this myself and the shaker won't fit on my air cleaner so i got a whole ***. off of a 79 with the cleaner too. it does need a spacer to clear the thermostat switch and to bring it up to the hood.

flyitlikustolit

but you're running the stock intake, right? I'm running a performer RPM.... it's a couple (3-4) inches taller than thre stock piece. the air cleaner clears the water neck just fine. my problem (maybe it isn't one) is that right now, on my car, i have the RPM intake. I put on a 1" carb spacer, and the carb barely clears the hood... the front of the carb is about 1/2" to 1" from the bottom of the hood.... if you remove the bracing first. what I need to know is, if I remove the spacer, cut the bracing out, will i have enough room to mount the entire shaker assembly. is there any way to find out? some one has got to have tried this on a car set up like mine.

i am using the stock intake and it looks like i will need about a three inch spacer to bring it up to the hood with the pontiac air cleaner from a 79 so if you remove the carb spacer and have the pontiac air cleaner if should bolt right up.

flyitlikustolit

bad @$$. I think this will work after all. I just bought one with an air cleaner and everything. how tall is your intakefrom the china wall to the carb flange? I'm going to measure mine tonight, and then the difference will help tell me what i have to cut off of the air cleaner.

I got the Shaker bug too! Just bought a 70-76 Trans Am shaker, because it has the largest opening. Didn't really think about clearance differences, but I'm sure I'll figure it out. I just got the scoop, a functional open one, so I'll have to fab the lower assembly myself, or get it from the local junkyard.

I was planning to put the shaker on "backwards," for a Ram Air effect. I think it will look cool. Any opinions? Looks aside, forced air on an X Stream filter lid should be effective. I wonder if the 3rd gen hood isn't too raked back for the cowl induction effect to happen on the shaker. Might be starved for air at freeway speeds, so I say, mount it backwards!

Got the scoop on Ebay, so I probably won't have it for another week or two. Will post pics when I get going. Good luck with your shaker project!

See pic of the latest scoop...

I've noticed there are a lot of threads on the shaker scoop. Maybe a 100th Monkey phenomenon, because I can't stop thinking about it.

There are those who think the shaker shouldn't be done on a 3rd gen, but they couldn't be more wrong. The carbed and TBI cars especially are begging for it, and the TPI cars merely await the fab savvy. Hood birds are a must also. Of course, the aftermarket ram air hoods are super nice, but the shaker's has more X Factor--don't see too many of them.

I'm planning to install my shaker bacwards--it's an early 70's version, for a ram air scoop.

You can also buy the parts, flapper, solenoid etc. at Tachrev.com, if you want your scoop to open and shut. They've also got complete kits. I got mine off Ebay though, for 40 bucks, and I will fab whatever assembly I need. My TBI makes a glorious sucking sound as it is (no comments please) so with the scoop I should be rockin. Found a pic on another thread of how mine will look:

flyitlikustolit

I got your email, and I'm still trying to find a tool to cut the hood with. I made a template from a hood i got out of the junkyard. the hole is the pefect size, just in the wrong place, so I also have some basic measurements. I'll gather them up for you tonight and post them here. good luck. it looks like your scoop is shorter than mine, so it'll fit better.

Poncho Villa

That would be great if you posted measurements. I was wondering about that, how to locate the opening. I will still somehow mark the underside of hood for center of the TBI--mount a grease marker on my air cleaner or something, then figure out where the scoop will mount relative to that center.

The other thing is, making the edges of the hole clean. Was thinking of putting blue painters masking tape on the paint where it will be cut, so it doesn't crack or flake, then pull off the tape after cutting. Then using a dremel tool to round the edges.

Of course, we will need 2nd gen hood birds next.

flyitlikustolit

definitely. rounding the edges sounds good. I'm going to cut it tomorrow, so I'll tell you how it goes. wish me luck.

jocww

you should ask this in fabrication

flyitlikustolit

i will, (especially if you're telling me that there is a distinct possibility that I'll get an answer.)

Mount a cutting wheel on a small angle grinder, works great. Just be careful and cut slow so you do not heat up the metal too much. Used this technique to cut the opening in the hood on my son's sunbird, clean cut, no warpage.

Cut the opening out of the junkyard hood, then cut your hood, then weld or bond the flanged opening to your hood. Little smoothing and you should be good to go, and it will look almost factory.

sailorrick

Does anyone have a pic of the finished hood?

never mind I just seached and found some, I think thats somethinmg I'm looking into doing.

Remyr

Will this work/look right on a Camaro? I need to get some more air to my nice shiney Edlebrock open element air cleaner. I can tell a major improvement just with that.

flyitlikustolit

I'm taking the cut-off wheel to it this weekend. the hood i found in the junkyard was off of a 2.8 MPFI firebird, not a 2nd gen. it's not flanged, it looks like someone cut it with a plasma cutter. i figure with some epoxy or fiberglass resin or something I can form a rolled lip around the edge of the hole I'm going to cut, so when it's painted, it'll look good. I'm marking the outline of the template on my factory hood, and the I'm going to cut the straight parts with the wheel. when i remove the plate of metal from the hole, I'll shape the edges with the cutoff wheel, a recip saw, and an angle grinder. I think it may work. if not, I'll paint the bastard and stick a set of butterflies on the intake. or a bug catcher.

Bills87Firebird

Hey the dork working on that 87 firebird with reversed shaker and putting the pink strips on it is me LOL
I cut my hood with a jig saw was pretty easy and you can not mount the scoop like it should be no clearence even putting it on backwards you will need to remove the rivits and repostion it but once its on it works fine makes a good ram air.
BUT think about the rain it sucks hard to seal and sucks it down easy.

Joshua Bennett

what i would do is , say if you needed the hole to be 10 by 10 for example I would cut it 9 by 9 and at the corners cut 1 inch in and fold all 4 sides over to form a bur free lip

i was thinking of doin this mod too because the 2nd gen was a major influence on me about f-bodys but i love the 3rd gen a lot though. i had been thinking this for awhile but didnt think anyone has ever tryed it but now i have lots of info. only thing will be is finding the center of the carb on the hood. but once i get it all done it will be haul a$$ time

Thats the easy part! Install the hood you are going to use, thread in a long carb stud, and slam the hood! The dimple will show you exact center!

steves86TA

If it dosent break the carb... or will it ?

custom88camaro

It definitely could break the carb, depending on how long the carb stud was. I think I would unscrew the stud just a little, then close the hood (lightly) and see if it hits. If it doesn't, unscrew stud a little more, then close hood. Try this until the hood is definitely hitting the stud, then jiggle the hood on the stud. It will scratch the paint a little. Drill a small hole from the bottom and you will have a refernce point. I think that's how I would do it.

Air_Adam

Unscrew it till it will touch, then put a chunk of play doh or something on the tip of the stud, so it will stick to the hood.

Bills87Firebird

Lay the scoop on hood trace around it get the scoop centered first you can always ajust the scoop on the Aircleaner by removeing the rivits.

flyboy367

go to the fabricating forum. there is a full detail writeup of the shaker hood in there. it has pics too.
