Hi
I've had 8v71's before.
That seems high to me,look for some old truck wrecking yard.I bought a cutoff cab and engine complete for $200 with a running engine that had Jakes on it.A complete AM rebuild kit was under $1000 when i did an inframe on mine.
These were a popular engine,Often refereed to as a 318 Jimmy.They were used a lot in buses.Make sure that whoever installs the Jakes knows how to set up the injectors.One guy i had do some work on my 671 didn't set things up right and it ran away.... .Scariest time i'v ever had working on trucks,it was my fuel truck with about 2500 gallons of fuel in the tank.The engine sounded nice...then began to rev up....and up ..and up..it was sreaming away he was trying to block the air with a piece of plywood and it kept racing away.I grabed a filter wrench and spun the filter off and it died.My face was about a foot away from the block as i'm trying to spin the filter off,all i could think about was a rod coming out at me.
