Im throwing the idea of putting a 6.2diesel in my 79 k25 gmc to replace my 5.7 gas engine. My cousin said I could have his 6.2 turbo diesel since he has nothing to put it in. He went over it and rebuilt it and he has been around diesels all his life he says Itd be a good swap.. I know it's not a powerhouse but I don't tow anything and only evr haul around 3000 lbs but thats even seldom. I want a diesel for good mileage and the low end for running around on hilly roads since I live in the Alleghenies. Any input would be appreciated
