what are all the things you could do to get the most power out of a 6.2

 

sell it!!, maybe turn the pump up a little but then beware of the head gaskets....

my 83 chevy 3500 dump truck is unfortunately powered by a 6.2

 

gears and rpm's......my truck runs best with the turbo 400 and 4.10's out on the freeway with 265/75/16 tires......my speedometer is correct and my truck will run 85+........not bad for a 1986 3/4 ton 2wd Suburban with 225,000 miles on it.........turbo from a 6.5 would be good with a few pounds of boost......
