Hi: I just joined the forum. Lots of good information on this site. I just bought, about a month ago, a 68 Z28. A real barn find. I live in rural Midwest. I heard about this 68 Z28 that has been in this barn for 33 years that was for sale. The guy I bought it from, bought it in 1980 from his brother. It was about 5 miles from my house. It did not have the original engine. I know where this is going! The guy I bought it from knows what happened to the original engine. It is not to be found though. I also know the 2nd owner that bought it in 1970 from a Chevrolet dealer. When he bought it, it had 302 emblems on the front fenders. The car was built in Jan. Therefore, 302 correct for the build date. The car does have the original M21, 12 bolt, power disc front brakes, 3/8 fuel line, rear bumper guards, exhaust hangers on the rear frame rails. But the tire decal in the glove compartments has 14 in. wheels. What is up with that? Is it possible the wrong decal got put on at the factory? The car is from owners documentation a Z28. In 1970, they did not have to clone a Z28! Will update as I progress with restoration.
