I had a 94 impala ss (LT1)and it was a pain. There was always little things wrong with it and the plugs were like an all day job......... my girlfriend would always make funny of it and would tell me that it would never be as quick as the mustang with serious money and work. I eventually sold it.
My '79 Z28 was a pita to change the rear plugs in, for sure, much less try to tighten the rear header bolts! But it had more room than the more recent z's
