Hi
They are both electronically limited. 129 for the 327 and 118 for the 355 due to the drive shaft. Each limiter has tolerances of its own so they could have differences as well, that's why it came in at 128. It could have easily done 130 as well, within the tolerance.
The 4 valve requires premium fuel and has a lower top speed. Its been considered by Ford but drives the cost up several thousand, which police agencies don't like.
Thanks

In your 2004 police vehicle test the Ford Crown Vic with the 3.27 rear gear ratio had a top speed of 128 mph and the 3.55 rear gear ratio vehicle had a top speed of 118 mph. Were the top speeds electronically limited or true top speeds limited by aerodynamics. If electronically limited, why? Were their speeds limited due to vibration caused by the driveshafts? In Florida, I have seen several Mercury Marauders FHP vehicles. Would like to see the test with one of these (32 Valve v-8)302 hp vehicles. Is MSP considering the mercury Marauder? Thanks for your time and answers.
