Cop cars on Island

We had 440 Plymouths, here in Pa., at that time. http://www.allpar.com/squads/collecting/photos/monaco.jpg
I came drifting over a hill one time in a 63 sport fury, on my way home in eastern okla., was doin about 95, no traffic, good 2 lane hi way. topped a little hill, there was an okla. hi way patrol setting in the bottom of the 2 hills. I didn`t let off or hit my brakes- I was already caught! These little hills (knolls) were just high enough u couldn`t see the bottom of them till u topped them. the patrolman was in a 68 fury, he was setting still , a right angle from the road, and he caught me before I got up the next hill. I had to go set in the cruiser w/ him while he wrote me up. That fury set there and shook the whole time like a big engine w/ a big cam, in it. I was young and noticed it, but didn`t have a clue.
To this day , I think that thing had a hemi in it. I`ve had two hemi`s, (ONE HAD A 785 LIFT CAM DYNAMICS ROLLER IN IT) and 383`s, and 1- 440, and my 505" wedge, none of them shook like that patrol car!???????? sorry for long post!
