I supposedly have a 1991 trans am ws6, from what the guy told me when i bought it im only 17.. the car doesnt have sticker for rpo codes of any thing but it does say "performance suspension" it is a 5.7 ltr auto car> can post pics but car has been repainted.. it does have some gay blue neon under it too.. if that helps

 

run the vin, it is a good place to start (plz don't ask how, get your parents involved if you can't figure it out)

then, go to the block and get the numbers from the LO3 engine......err 5.7

do a search on this site and you will find at least qty 50-100 threads on where to get the block casting #s and how to translate them

 

Go to this site and put in your VIN and it should tell you everything your car came out of the factory with. What's happened since then you'll have to figure out. Have fun!

I wouldn't put too much faith in that website henryd3!!! put my vin in and it had no database for an 88 TA. personally think it sucks. Datbase should be there after all these years.

 

Well, it's only a suggestion, it worked fine for my 92 Camaro and I figured his 91 TA might work as well, you have a better idea?

 

yes, he's 17

get his parents involved. They will make one quick call to their auto insurance company who can run the vin. Since he can't get insurance on his own and is riding their policy, they must make the call.
