I agree,the L10 is a nice engine!!
we just did the testdrive in the donor truck and im very happy with it.its hard to compare a empty tractor with my loaded bus,but it feels good so far.
now i have to decide if we take it one step up and even use the 9 speed manual or search for a ht 740 or b500??
i think it costs more to change the ecu settings on my ht748 to lower rpm and shiftpoints,then changing transmssions.
i have to admit,that i have a interested buyer in my engine tranny combo,and he wants the whole setup to make his swap easier!!! this would help me with the hidden costs that will show up while installing the new drivetrain.
also the transmission choice will give us the factor what rear end ratio we will use.
still lots of questions!
