does any one know anything about the '70's , 80's 6dr50a engine? Dodge put a few into their late 70's trucks and mitsu ran them in their (i believe) canter/fuso style trucks and lift trucks. Are they any good? Seems to be a little low on horsepower (105) naturally aspirated, but I imagine a turbo and pump tweaks would work wonders. Any parts availability? Any sort of manuals? thanx
