Just bought my bird about two weeks ago, and I'm wondering if anyone has factory specs on it.

It's a 1989 Formula with a 305 TPI, 700r4 trans, ws6 suspension package.

Also if anyone is curious, I paid $3500 for it. 94k miles, very clean interior. Perfect exterior minus one or two slight but noticeable scratches, and a Grand Am spoiler (lol). The previous owner has a shop bill of $800+ worth of work done in February, including all new fluids, all new filters, new exhaust, new alternator, etc. After I got it, I replaced a headlight motor (God help me) which was ~$110. I've heard a couple people say I got a pretty good deal, so comment if you'd like, but that's not the main point of this thread.

Anyway, was wondering if anyone has the factory specs for this, mainly what the factory rear end was in it, and the curb weight.

Thanks!

Should be 2.73s in the rear-end. Weight should be in the 3300-3400 range. Looks like a good deal for the money.

Thank you. Everywhere I went for curb weight, it was all "no data." Couldn't find anything for factory rear end either.

So far I've seen numbers ~15.9 for quarter times, that's slightly disappointing. Going to work at dropping a 350 in it, and see what happens from there.

the 305 TPI autos were slugs because of the 2.73 rear ends. Those are what kill you, but there good cruisers for those gears if your using it not to race.

Center console was empty when I got it, all that's left is a little glue residue that used to hold it on.

Also, I'm definitely going to race it at some point or another, so I'll look into getting a better gear. Any specific suggestions?

G92 off a third gen is the best factory one you can swap 3.42 rear end disc brakes or find a 98 or up 4th gen rear end to swap

My completely stock 87 Camaro with carb LG4, auto, and 2.73 gears was doing 15.9's all day. I suspect a TPI should be a little faster

Alright, that's comforting. I've been looking around a bit, and I've seen Formula 350's around mid 14s.
