"The 11 small block Canadian pacecars (out of 22 built, plus the AJ Foyt replacement Pacecar with A/C) weren't even SS'es. They were all LF7 327/210HP Rally sports. Just a little tidbit of little known info.
Don't qoute me the old USCC article that says they were L48 RS/SS'es, because its wrong, I've seen the GM of Canada paperwork on these. None of the SB cars are SS'es."
I can vouch for what Mark is saying...since I am Canadian and my first Camaro at 17 was a Canadian Pace Car - and it was an RS - I've got the GM paperwork on the car to boot. Also, I was contacted by a fellow in Grimsby, Ontario 2 weeks ago who has one also. I can email you his trim tag for proof if you need it
BTW, it has the - code after the 5BY also and 0-1 paint.
