I have worked on these cars a lot in the past. There are a few differences between 68 and 69 base camaros, like the 69 should have the ignition on the column, and the grille, headlights, and tail lights are different. The body sheet metal was similar in appearance, but hardly any of it is the same. The front side parking lights are moved to the front of the vehicle on a 69, they were in the fender on a 68. The SS had several different engine options, big and small block, and the Z28 had a special 302 CI engine, that was a high revver, it was basically a 327/350 block with a 283 crank, its own special cam carb, and intake. SS camaros also had cowl induction hoods, and the optional/rare big block option. Basically the SS was a drag racer, and the Z28 was a road racer. I want to post a link HERE with some additional info. There were other small differences, but these are the ones I recall. If you have any more questions, as always, I am here to help. Good luck with it, have a great day, and Thanks for using Just Answer.

The sheet metal is different on the 69, there is a body ridge that goes down the side, most people don’t even notice it. Also a lot of pro's say the 69 looks sleeker.

Most of the time cars like this are a combination of an investment and a toy, so with that in mind, your are in good shape investment wise with a 68, or a 69, as long as the car is solid, and the price is right. What I would do, is to buy the one you personally like the most. There is a cult following for the Z28, but the big block model is faster. So which ever one you like the best, I think you will enjoy the most. I do however recommend you get an independent mechanical, and body inspection, then appraisal. Some muscle cars are cobbled back together from rusted hulls, and others are garage queens, and true treasures. Study what they have been selling for if you can find any resources. The independent mechanical, and body inspection protects you in many ways from buying a, for lack of better terms, a prettyied up turd, or a true collectors treasure, I have seen plenty of both, I cant overstress how important this step is. You might also check with the local BBB if it is a dealer, and see if they have a good reputation. If you have any more questions, as always, I am here to help.
