I'm looking at a mid "80's GMC 7000 s/a dump with a 366 and a 5/2 setup.What's the overall opinion on them?Longevity,mpg,power ect...???
i have a '79 C65 chevy with the same combination. When i first got the truck there was really nothing impressive about it. the truck just delivered the loads. after having it for 3 years i am now impressed. it is cheap to repair, doesn't require a computer degree to work on. and has done what was needed every time. there is nothing flashy about it, would I buy another definitly if i didn't put high milage on it.
