That makes one of you! The 3.5 is a revver, but the 3.3 and 3.8 are
tractor engines. And the 3.5 really isn't a slouch on the low-end
because its got variable manifold tuning. They don't have AS MUCH torque
below 3k as a 318 or 360, but they're about a hundred cubic inches
smaller, too! Compared to similar-sized engines from Toyota and Honda,
they have a LOT more get-up-and-go off the line.
You must have much different tractors where you live! Neither of my
3.3L engines will accelerate much at all below 2,000 RPM and don't
really begin to pull until 3,000. And when I come to a grade at all,
the transmission downshifts twice to maintain 60 on any significant hill
in northern PA. My Acclaim with the 2.5L would pull most hills around
here in high gear with only the occasional unlocking of the TC clutch.
It took probably 3/4 throttle to trigger a downshift. The 3.3 will
downshift at what feels like 1/2 throttle or less. I never meant argue
that they have the same absolute value of torque as the old larger V-8s,
I meant that the torque curve is much less flat and peaks at a much
higher RPM. It is the character of the engines, not the absolute numbers.
