weird uses for a slant 6

i saw one that was used to run a winch set and hydraulic pump unit for an old log jammer (skidding machine) that was hand built in the 60's. very interesting piece of machinery, the guy said he had a 396 BBC in it before and it kept overheating, couldnt handle being at 4000 rpm all day long. the ol slant however was ran wide open all day 6 days a week, never had a problem, and would skid logs up the mountainside like nobodys buisness.
