1970 440 Police Interceptor?

The Father of one of my friends owned a wrecking yard and one weekend his Father was gone on a trip.
He called and told me to come down and pull a "Police interceptor" 440 magnum for my 69 Roadrunner.
At the time I had the original 383 Magnum in the car and it was in good condition and ran really good.
The first time I put that pedal down with the 440 in it I could instantly notice the difference.
Both engines ran the 800 Holley and what a frickin power monster for a basically stock motor.
160 on the freeway was easy, but I was too nervous to take it faster than that but it had pedal left.
I could enter the freeway at 60 mph and step on it to kick down into second and easily spin those Micky Thompson radial tires up to over 80 mph. (yes both of them :-))
It was kinda scary in the rain because on the freeway at 55 if you pushed the gas a little too much the rear end would start walking around.
