So I receive my CHevelle a few days ago, a I compare it to my original version, there's a few differences, first on the front bumper, the turn signal are now molded on the bumper, un unfortunatly the hole are plain, so we must do some "cutting" job to clear them. The famous rear tailights have been improved a bit, and there is the seperate chrome line between the "have to paint" red part, which is still molded too deep anyway. There is a lot of molding line on the body, but nothing too serious.
Concerning the engine, on the original issue, there was no choice for the 396, it could only be built as a "street machine" engine with chrome manifold and injection. On the reissue, they put a few parts for building it stock, with "flat" valve cover, four barrel carburator and manifold and a classic but not accurate air cleaner ( normaly we should have a chrome element if I'm right ).
Hope I'm clear enough on my explanation, I'm sorry I didn't take pics but time is missing as always
