So just how good was the A-Body back in its day?

I had a friend that's Dad owned a 40 Ford with 327 fuel injected 375 hp. One night Bill's Dad let him drive the 40 and he looked me up to run him. We went to a familiar place and lined up and I beat him. He got mad and said he spun out and wanted to run again and roll out so I said fine whenever you get ready you hit it. That was right down my alley since I have always had traction problems. When we got to about 30 mph he took off so I let him get the jump so there would be no excuses. When we got to the end he wouldn't let off and I knew if I did he would say he beat me so I stayed in mine and could see him in my rear view so coming up on slight curve I moved over in front of him. He was really mad that time and said I cut him off so I said to him there was plenty of room for him to come around. Anyway he parked the 40 and got in the car with me. We ran across a guy that had a 56 Ford with a 427" Ford in it. Bill hollered and told him we wanted to run (he was trying to get me beat) we went back up there and I outran the 427" . I pissed a lot of people off! Man was it fun though!!Can't do that now with all the traffic. Back then most of the cops knew all of us and unless you got smart with them they were pretty easy on us. One time they were raiding the interstate where we were racing and I was coming back to the line when I saw a whole line of cops coming up the on ramp. I saw them in time so I shot off the off ramp and got away.
