on a thread in the nationwide section of DB a canadian BOMB'er brother talks about his boat engines. [posted below at the bottom of this post]
i never knew they were available with alum blocks. WWII era.
boy, thse inline 71's had a long manufacturing run time. i remember how popular they used to be severl years back.
you could take a photo of one of these detroits, hang it on the wall, and by morning the wall and carpet would be soaked with oil.
below is the post about this guys boat engines.

Thanks for the link to GMC Engines. You're right - I didn't know about the V6 gas to diesel conversion. How about these obscure variations: I had twin 6-71s in my powerboat - WWII vintage, aluminum blocks, hydro-starters, pyrometer on all 12 cylinders - and both were connected to a single Allison hydraulic 2:1 reduction/reverse gear turning a single 38" propeller. I could run port engine or starboard engine as a stand-alone engine or both together for main propulsion, or alternatively, use one for propulsion and the other for pumping (bilge or firefighting) or PTO or whatever. GM made various configurations for different applications (marine, Sherman tank, industrial, genset) but all engines were connected to a single PTO or shaft: single 6-71; twin 6-71s (side by side); tandem 6-71s (end to end); quad 6-71s (side by side AND end to end). Very versatile power!
