Looks like it could be made to work, but like already mentioned you would have to remove the front section of the Chevelle frame and graft on the front section of the Impala frame, the front wheel wells on the Chevelle are molded into the frame, and on the Impala they are molded to the body. Plus you would probably need the front section for mounting the engine. May need other mods to make everything line up. It could be done, but too much work for me to take on. I'm going with the stock version of the Impala, the Chevelle is all Pro Street and has a nice set of big slicks for the rear.
