Origin of power stroke engine

The tm 6.2/6.5 motor was a ground up diesel from Detroit. The 6.2 was spend and designed as high mpg 305 gas motor. Ie similar hp/ torque specs. The 6.5 350 hp spec, 454 torque wise. Good motors for what they were spend as, many like those with the 350 diesel, and to a degree the Ford idi6.9/7.3, and first generation or two of the b5.9, went .me Tarzan, I have diesel motor. But none of these were that chest thumping powerful.

Th only thing the same about the idi7.3 and PSD 7.3 is displaced,event. Similar to the new cm 4.3 v6 and pre kids version, displacement only.
