So I am looking at buying an '87 TA GTA w/350 TPI......I LOVE the older style bulge hoods and want to add it on. I am guessing that since the 87+ Formulas have a bulge hood, one could be fit onto said '87 TA, right? That being said, with TPI....I don't NEED it to be functional, but I would like some extra cold air getting into the engine compartment. Is there some way to set these up for that?
Any help is appreciated. :hail:

The cowl induction only works on the crossfire injection, carb, and tbi units. There is a difference between the one for crossfire and the one for carb/tbi, they don't interchange.
As for the TPI, it has it's inlet in front of the engine, not on top like the carb one. It would have to be some serious ductwork to make that happen, and I really don't know if it has any advantage at all.
You could of course just use it without the induction piece, it would make the enguine bay a bit cooler, but it won't help your intake charge much as it goes forwards, and not backwards.

BTY, look for used, new they are about twice the price for the Formula hood. There are a lot of good hood out there, most of them are on the 87-92 Formula since they used some better sealers in the primer than the earlier 82-84 ones.

I will keep that in mind if this deal goes thru (or I end up with any 3rd gen TA)

i was wondering why i was seeing firebirds with 82 83 84 hood and no fender side vents! doh!
i dunno about bad sealer on 82 83 84 ones, my 82 one is fine no cracking or anything on seams, and thats after sitting out in weather in casper wyoming for years and now here in central IL, read that as cold cold cold ice ice ice snow snow snow rain rain rain, both here and out there in casper, most all of the year cept for a few weeks maybe, then its damn hot sun beating down over 90's sometimes over 100
and it sucks that 82 LG4 cars got ripped and didnt get functional scoop
dammit!
i want my 82 hood to have the parts under it, i dont want the dual snorkel 82 LG4 non functional setup- that it came with and has- on it,
i have yet to see a functional hood setup on an 82 83 84, just plain rare as hell, at least here anyways, ya'll that can find the parts for these hoods you are who i am jealous of!
you suck!!
big time!
thanks

The difference between the '82-'84 T/A hoods and '87-'92 Formula hoods is the removable piece on the scoop is metal on the '82-'84's and plastic on the '87-'92's.

my 82 is LG4 and it has power bulge,
it is a WS7 with the rear axle it has, but it has WS6 sway bars,
if it werent for the rear axle not being disc then it would be a WS6
personally i am 95% sure that my 82 LG4 is one of the WS6's that got ripped off and didnt get the disc rear it was going to get for that year, especially since its higher sequential production unit number(look in my signature info)
so i think youre trying to say that WS6 birds were not supposed to have LG4, or that LG4 werent supposed to be put in WS6 birds
what do others think ?
im curious
were WS6 LG4 birds built, or were no such cars built ?
if not then how do you explain my 82 T/A?
i want to learn

If I remember right there was a shortage of the Buldge hood in 1982, and that is why some T/A's got the flat hood...

I don't know about lg4 ws6 82 models, but my -87 formula has ws6 (standard on formula) lg4, (base engine) and rear drums. It has a 3.23 rear axle ratio and limited slip. Perhaps the rear discs isn't part of ws6?

Early on the WS6 was Disk brakes, and the WS7 was Drum brakes, everything else the same...
Somewhere between 1985-1986 this changed and WS6 could come with either Disk or Drum rear brakes.

On the two '82's I've had and the two '83's I've had they are metal. The '91 Formula that I parted out was plastic and I have a hood from an '89 Formula that I will check.
On the T/A WS6/WS7 was available with the LG4 and standard with the LU5. My '83 LG4 has WS6 and my old '82 LG4 had WS6 as well.
On the Firebird S/E you could get WS6/WS7 with any of the engines including the Iron Duke.
I am pretty sure I read that the turbo hood was apart of the WS6/WS7 package on '82 T/A's. I think this changed mid-year. All of the flat hood '82's I've seen were non WS6/WS7. I don't believe there was a shortage of the hood (although I can be wrong).

82-84 10035292
1987 10035292
1988 10035292
1989-90 10035292
91-92 10035292
According to the PArts & Illustration catalog they call out the same part numbers for the "Hood Ornament"
I also see in that pic there is the "screen" that was used on 82-84 cars, and the Firehawk...

We added that screen, it's from an '84 T/A.
Hmm, the hood had it's original red paint and silver decals when my friend bought it from the junkyard.

Since our cars were made in an assembly plant, no parts were produced on site, they wer all shiped in from elsewhere. It may be possible that during some strike the plastic Ornament could simply be from a strike somewhere when they could not get the cast parts, and they had to resort to someone else producing the part...
Just a theory...
