I need your advice! I've got a 351W in my 89 Crown Victoria (police). I
find the accelerating too slow from a stop, but there is a lot of power at
high speeds. At 140KM/h (85mph?), the RPM is only at 2000. I tought about
changing the differential ratio (3.75), sacrifying speed for performance.
Of course, the differential locking mechanism would be rebuilt (clutches and
discs) because it slips too much on winter.
The second option would be to replace my stock carb for a 4 barrels &
intake. So, the RPM will stay low on Overdrive at higher speeds.
I sometimes go on the highway, but more city driving. For the same price,
wich one of the 2 modifications would give me the best performance from a
complete stop, thinking about gaz mileage.
I already changed my exhaust system for 2.5" in dual exaust with headers, so
this should not be restricting performance.
Come see my car!
