216-235 with low pressure oil system and Babbitt bearings ................would be on the avoid list if high speed cruising was the end goal.
4 speed with granny is pretty much useless in “normal everyday driving.”.........no matter the engine choice. Been discussed here many times. Granny 1st gear is great for parades.
How do you figure? You saying any transmission with a final ratio of 1 to 1 is useless? I will respectfully disagree.
The sm420 transmission is the stoutest truck transmission ever made, useless is a far cry away from the truth and as bold as you said it, I will say the complete opposite. See how long one of those saginaw 5 speeds will last in a 2 ton bigbolt.
