Best thing about the car is the interior, it looks about a year old... not 25. Its had a ton of tune-up/ maintenance work done on it recently and runs like silk. I like to buy cars that are original and unmonkeyed with, and this certainly is that.

Guy I bought it from is a full time mechanic and has had 80's Camaros for years... its his thing. I have a real good feeling about the car.

Don't sweat the auto, you can easily make it a real tire burner. My 305 in my C2500 has a similar combination. It's a factory-rated "235hp" 305 with a 4L60E behind it. 14 bolt SF with Gov-lock and 3.73 final drive. It put a hurt on my buddies 87 Mark VII LSC with the 5.0L HO (not the regular lame 5.0L most Mark VII's came with) all the way up to 60 mph. That's in a 3/4 ton extended cab truck with 31" tires. The strong first gear and steep final drive can easily make these cars little jackrabbit "light-to-light" cars.

If that Q is for me... To be honest, I'm not sure! I believe its the 10 bolt and it has limited slip, but I don't know the ratio. I got down on it a little on the test drive, its not that fast but it will turn the tires over, runs about as good as I would expect a 305 to run, doesnt seem worn out and doesnt smoke.

I pick the car up tomorrow.

Now, my 14 year old girl has seen some pics of what the car will look like with good paint and wants it!! My 20 yo son, who has a 95 Camaro, is getting jealous and trying to pawn his off on her!!! WHAT HAVE I DONE??!! :rolleyes:

So much for makin some money on this thing!! LOL

Hey, thanks for those great tips!

Its a 1987. all stock TPI etc.

I'm sure it will stay stock, I was just kidding bout the 4:11s (well not really haha)

If you see my recent post, now my daughter wants it... I think it would make a great first car. Its drives and handles really nice.

a ssomone who had one for a first car, i would say it is not a good first car
#1 they suck in the rain or any bad weather
#2 enough power to get into some serious trouble with
#3 they fold up like an accordian if u crash them

my first car was an 87 iroc with the 305/5 speed combo lots of fun and great car but i got in alot of trouble with that car and had lot of very close calls with it

if u do do gears get a set of 3:42 or 3:73's max, though id have to check what the 305 came with i know the 350 cars would be either 2:72 or 3:23 not sure of the 305 cars were the same


is the rpo sticker still under the center console lid ? if so take a picture of it and i can tell u what gears and suspension options the car has

i've never owned an iroc or 3rd gen z-28, but i've owned 3 3rd gen camaros (sport coupes).

1) i hope your back is in good shape because they ride rough. This is not necessarily a bad thing, but i want to point that out to you.

2) No real problems, easy to work on. i didn't have an easy time in the snow, but think this has more to do with tires than other things such as RWD, more weight up front etc. i think it's generally a well built, well designed car.

3) These cars really handle well. So, at least with me, they kind of intrinsically made me want to drive a little more aggressively than what i would normally do. This got me into trouble occasionally. So you have to be careful about that.

My first car was an anemic 1984 Caprice Classic sedan with the 305 and an automatic. I still found ways to make that car a terror to fellow drivers on the streets. I still have the car and now I have to fix everything I did to the car when I was much less responsible so I can have a nice sedan for the family. The misses wants a mid-size SUV so there's no chance of me getting a new truck anytime soon, so I have to dust the cobwebs off the old Grandpa car and make a decent cruiser out of it for the family.

I guess the point is that I agree. Even if your daughter wont thrash it, I'm sure whatever guy she's dating at the time probably will. You have a nice car though, I really want a 3rd gen as my next project. These cars are starting to climb in value and become real collectors. Hold on to it before you kick yourself for getting rid of it a decade from now.

I´ve had my 1986 3rd gen Camaro 20 years now and done just about everything to it that I could.
Living where I do in Spain I got lucky and am not restricted by laws on modifying it. It was imported as personal belongings and many mods were already done.
Lowering the car and adding subframe connectors made it even better, I also upgraded to a 355 from the 305, no one knows at the test center, one V8
is the same as the next.
I did use the computer Quadrajet for awhile on the 355 with another computer and chip but eventually went to non computer completely.
At the time I got it HotRod did a 1982 3rd Gen "makeover" which I devoured and would have liked to have copied.

Theirs eventually went to the crusher....:( very :(

HotRod Part one.
HotRod Part two.
HotRod Part three.
HotRod Part four.
