Interesting, but a couple points could be argued..
He mentions not having 4 bolt mains but he didn't mention that the AMC 2 bolt mains are massive with 1/2" bolts. Other small blocks use smaller mains and bolts.
And it is easy to answer this question that he has: "Jeep never used the second-gen AMC V-8 and instead sourced a Buick-derived 350ci with a very flat torque curve for 1968 until 1971. We have not yet found a definite answer as to why." It is because AMC didn't own Jeep until 1970.
