A good deal gone wrong..my 1985 k10 diesel build.

[ol'blazer]

I bought this 1985 k10 as a work truck, i paid 800 for it and it ran nice and drove the day i looked.. but when i got home and started going through the truck that i found that the temperature quage was either running cool or over heating. when i checked the coolant i found that it kept blowing back through the rad. I have a blown head gasket, or cracked head.. i guess i should have gone through the truck a little better before buying it....
anyway i decided to make this truck into my winter project and fix the head gasket and/or head. add a 6.5 turbo with about 7-8 psi, and make it pretty!
