Any emissions labels under the hood?

If you are referring to the Service Parts Label Identification Label, it should be located on the console door. It includes the vehicle identification number, a listing of option codes, paint type, paint cade, convertible top code and an interior trim code.

The 5.7 (350) was the standard engine in a GTA.
If it's a real GTA and it's an Automatic then it's a 350.
The only way to get a 305 in a GTA was if you ordered it with a Manual Trans, and then it was a Credit option.

Lets see,black over black,16 inch gold lace wheels with the rear being wider than front,small gold birds on the c pillar,and badges on the fenders that said "GTA Trans Am",GTA Trans Am badge on the nose,GTA Trans Am emblem on horn button of steering wheel.

1987 Pontiac Firebird Trans Am GTA introduced, available with the LB9 305 TPI motor or the L98 350 TPI. Gold 16" flat mesh diamond spoke wheels standard on '87 Firebird GTA

87 IROC-Z
Formula
Trans Am
GTA A4 LB9 V8 9.3:1 5.0 (305) 190@4000 295@3200 TPI ---- ---- 2.73 3.23

Agreed, '87 was the first year for the GTA and the intro of the 5.7 in the 3rd gen F-bodies. The GTA could have the 5.0 TPI or 5.7 TPI same as the IROC. I'd recommend getting the '92 as only 508 GTA's were made that year.

Almost bought a red 92 GTA back in 98,but it was a hardtop.stupid me it was probably a rare GTA being it was loaded and a 350 with no t tops

Any GTA in '92 would have been a rare find although I'm guessing red was a popular color. I can't remember if it was '90 or '91 when all 350 equipped GTAs had to be solid tops due to torsion concerns with the chassis. I know in '89 you could still have a 350 T-top GTA.

In 1988, you could get a T-top GTA with a 305/automatic as a credit option. It didn't HAVE to have a manual. Mine is a verified true 1988 GTA Trans Am with a 305/auto and t-tops. I have since made it a manual, but it is a true GTA.

If you need more verification tips, I'll be happy to help. I have the creator of the GTA on my Facebook friends and we DO talk.

The 305 has an F in the 8th digit of the VIN. The 350 has an 8 in the 8th digit of the VIN.
