Match Race ~ 1968 Road Runner '383' vs. 1966 Mercury Cyclone GT '390'

Me being a relic from that era I can only tell you from memory that driving a new 1970 Swinger 340 dead stock, neither of those vehicles were a problem to the Dart. Stop light street races were very common then, and so there were many opportunities to "compare". The Ford 390, as someone has just said, were considered a dog, even in the Mustangs. The 428CJ was a whole different story though. I was pretty cocky with the Swinger because I had found that it was much faster and quicker than I had realized when I bought it. So the first time a Mach 1 pulled up beside me at a light I saw the "428" and thought "oh well" just a bigger 390. Figured I might have him by 1 -2 car lengths instead of 3 -4. Taillights. Very embarrassing. We had a drag strip near Toronto at the time and I saw the guy out there a few weeks later. He had more than 1/2 second on the Dart; both cars dead stock. The 390 Mustangs were low 15 cars, not sure what the Cyclone/Torinos would have run but probably a tenth or two slower.
