Yes, its just an old truck. I can tell you from seat of the pants, it would waste my 5.7 challenger, and my 6.4 truck would also not stand a chance against it.
Power shifting the old NP435 is about impossible, I can hit 2-3 no problems, but the 3-4 easy shift I have to use the clutch to get it to go in at 6500 rpm.
