the added weight of the car will make it stall higher
the lower torque output of the motor will make it stall lower
the gears, higher numerical gear will stall higher (I think) and lower will stall, well, lower
add it all up and who knows, it might stall close to the same RPM but it I had to guess, I would say it will stall lower, because the 360 doesn't make the down low torque the 383 makes to spin it
