I think one of the rpo codes is actually called "hood for transport" or something like that. They must have put some plain hood on the cars to get it over to SLP where the SS hood was added. I had some 17x9 and 17x11 wheels painted white for my 96 SS. I put longtube headers on it and some other minimal mods like plug wires and coil. I never got it tuned before I sold it, but the guy who bought it ran a 13.4 in the 1/4 mile without a tune. Not bad for an automatic.
