Whatever you do just don't overheat it. I have had good luck with 6.2's....until they get hot.

Pretty much, yes. The weak point on them is the main girdle for the crank, and the harmonic balancer. I think you'd be lucky to get 250 hp out of one.

It'll be more than up to the task of daily driving and pulling light (less than 8k) loads. I plan on doing head studs and main girdle studs with my turbo set up as well. As long as you have the crank re-enforced, you won't have a problem with the engine handling the turbo.

thats wat im gona do i want it to be a daily driver because i do have a true one ton 4x4 for heavy stuf i just want it to be a daily driver with just a little sumthin under the hood for when i have to pull my freinds out
I have a Ford with a 6.9 and it's got a bit more grunt to it, and it DOES get pretty good mileage, but its my work truck too. I pull some pretty huge loads and I'm NA. Before I got the Ford, I used the GMC with the 6.2 for pulling some hefty loads. Not as big as I do now, but heavier than I should have and never had an issue. Not even with overheating and I have the stock tstat in it.

well thats what i got to is a 86 single rear wheel f350 6.9 4x4 with a lot of work done to the truck and for N/A i make some pretty impressive power out of it, and the 6.2 i have i bought for 1800 with 40,000 original miles on it, an old man had it ever since it was new in 84, its a black gmc half ton shortbed 4x4, its very nice and id like to keep it looking good and just make it really nice daily driver and offroader that will go threw mud and pull out my dumb freinds
