There is no specific X-code for the SS350. X11 could mean SS350 with Style Trim or a base Camaro with Style Trim. A '69 SS required at least power front disc brakes. Also be sure to check out our FAQ section about SS's. The X11 code is the only exception to identifying a true '69 SS Camaro because the code also means a plain Camaro

X11" on trim tag on 1969's only 350 SS only but a big NO for a big block SS YES! not all "X11's" were SS's. Check the engine. If not original then assume the "X11" was for a base Camaro. Not easily added but check VIN to make sure it was a V8 because trim tags are getting swapped out. Also have seen people selling reproduced trim tags so watch out.
