I don't know; I have a 6-71 in my garage right now that still has the
Detroit Diesel green paint on it.  Some day it'll make it onto my truck.
Or something else.  They're getting harder to find nowadays.  Trucks
switched to turbos some time in the 70's.  I'm hangin' on to it!

Injection is nice but I'd rather be blown!
