some slants had a double roller chain and stellite exhaust valves.
...special versions for industrial, commercial, and marine use; these had special equipment such as two-row timing chains, chrome-plated upper piston rings, valve rotators, Stellite-coated exhaust valves, high-volume oil pumps, and polyacrylic valve stem seals ...

but did this define the QRS.......I admit I have no clue.....but was clearly depicted on the 73 Dart Custom I owned from new and as such delivered with the decal. This little car was notorious for chirping second gear on an automatic shift of the tranny....all you had to do was give it the gas...and hold it down....second gear....little chirp from the tire....

pishta....did not mean to gun deck you as they say....I should have define the question a bit by stating what I have written below this.....

The car was Canadian built and while I cannot say for certain as it has been so many years I am thinking the full decal was Windsor QRS
