I like the torque rating. I pull mountain roads in this area (Cotopaxi, Colorado). Torque is important to me. I don't need high engine rpm. You can't drive fast on these roads. I pull loads on steep roads. It only makes sense to use a commercial duty engine. After studying the engine design I find it superior to any other design I've seen before. I like the Cam bath and the high volume coolant circulation.
That's going to be a cool project, ur991! I had a '62 Chevy 4x4 someone had put a 305 V-6 in that was a great runner. but the body was shot. It had the sm420 four speed. I should have kept it to swap into something but needed some cash at one time.

When you say steep roads where you live that's kind of an understatement! I took this pic in the Parkdale, CO area 3 years ago. If I remember correctly this view is looking in the general direction of Cotopaxi! This is the Royal Gorge area.

Looking forward to following along on your build.
