What's up fellas? I have a quick question that I can't seem to find the answer to. Maybe you all can help. I am wondering about the production numbers on the '87 T/A GTA 5-speed. I found the number of produced GTA's to be 11,102 in 1987, but I am looking for the number of 5-speeds out of that 11k.

My apologies if this is in the wrong section of this forum, as I don't post much.

Thanks in advance.

I looked for one for a long time..My brother and I both found 87 Iroc's with TPI,5spds and 3:45 posi.. The TA's were very hard to come by..I bet they only made like 2,000 if that..The 5.7's didn't have t-tops.. The 5 spd's were faster also. I have owned both..

I think after 86 they resolved the T-Top flexing issue and 5.7/M5s were available... But it might be 88 that I'm thinking of. I'm pretty sure a bunch of the converts didn't get 350s though due to that and were limited to 305 TPIs (for the best motor). It's been a few years since I owned my 91 and my knowledge is dwindling to make room for 4th Gen knowledge heh

No the T-5 was not available with the 5.7L because it couldn't handle the torque of the 350. There was never one made. And sorry OP I can't help with your question...try Thirdgen.org

I heard that as well, but like I said I think they resolved that issue later on.

not sure on the 305TPI 5 speed GTA's (the 350 was the standard motor, the 305 was a credit option)

but i have heard in 89 you could get a 350 GTA vert as well as a T-top

the 350/t-top was a factory option, the vert was not... the verts were all supposed to be 305 TPI's but if you ordered a 350 T-top car and then it went to the dealer. At the dealer, you could then say "send that to ASC to be converted" for about $7k

i think there were ~ 50 1989 GTA Verts, as well as 2 1989 TTA verts

Well the thing is here, it's not a matter of no GTAs got a 350, but it's no GTAs got a 350 AND a manual trans. What I'm debating though is that I thought I remembered that problem being an early 3rd gen issue, and the later 3rds got a 350, manual and T-Tops.

Wasn't 87 the first year for the 5.7?

Nope, there was never a 350/T-5 from the factory in a Thirdgen.

And yes 1987 was the first year for the 350TPI.

Thats an impossible question to answer. Pontiac either kept very poor records or it has not released such detailed breakdown.

But 5 speed GTAs are pretty rare.

and Formula350--I think you are thinking backwards

There was never any unresolved powertrain combo. Maybe your thinking of the no 350 T-tops 90-92?

(except you could get a 91-92 Formula 350 with T-tops)

My 89 TTA has T-Tops so I would imagine all 89's could be had with them.

yeah up till 89 you could get any 350 fbody with t-tops

90-92 i wasn't aware ANY were available w/ t-tops + 350.. are you sure the Formula 350 you saw didnt have t-tops added later?

that one claims to be a 91 w/ a 350 and t-tops...hmmm

They never put a 5.7 in front of the 5-spds they were barely strong enough to hold the tq of the 305. And it was mid year 86 when the TPI 5.7 motors found their way into the fbods.
