Anyone can confirm if this is a On Road or Off Road version of the JL EVO 3 Tuned engine.

For some reason it's said Off Road on Towers web but is the same part number as On Road.
I guess it's mistake but it's always good to double check

COMMENTS: Some notes on Slide Valve and Rotary Carburetors:
Rotary Carbs offer a larger response in the middle of the power
band. This works well for off-road applications when throttle
response must be varied.
Slide Valve Carbs provide greater response at the beginning and end
of the power band. This works well for on-road and racing
applications for fast take-offs and high speed.
