I had my 2.5L up to 100 mph and it still had a little left on a level
surface. Dodge spec's list the top speed at 105 mph. I didn't check the
tach at the time (more interested in traffic at the time). According to the
rpm spreadsheet I have (downloaded from someone on the list awhile ago) the
truck was running around 4000 rpm. My guess with weight and wind drag I
was running closer to 4500 rpm (just a guess). In theory and without any
speed limiter, the little 4-banger could go about 125 mph at 5200 rpm (peak
hp and where the rpm limiter shuts down the engine, know this because once
I ran it to the limit in first gear, stupid I know). Of course I doubt
there is a straight highway long enough for the four cylinder to reach that
speed even if wind resistance and weight were not a factor.
The point is if my little 4 cylinder with a 3.92 rear-end can reach 100
plus, I don't see why the bigger engines couldn't hit 120 plus (without
speed limiter) with any of the rear axles. At least in theory.
As usual I've rambled enough.
