    My cosin got a rig. 77 k5 with a 4" lift 36" tsl Locked 14b and 44 front with 4.56 gears. To top it of its got a 32 spline sm465/205 combo with a hydro clutch. Very little rust for a New Jersey truck too. only thing wrong with it is the sbc is shot. So he wants to put in one of my diesels. I have from 82 to 88 6.2s and two newer 6.5s from hummer.not sure how to tell the year. Got the truck for 600. Has about 1500 to put a diesel together. has a bit more, but he wants to use that for other upgades. So what should i give him? As always thanks for the help guys. :bow:

    He will need the core support and the radiator from one of your trucks as well.
    I would give him a good 6.2l

    I agree give him the good running 6.2 over a surplus 6.5. I recently bought a surplus 6.5, the engine looked great interanally however it had a hairline crack in one of the cylinder walls. You couldnt see the crack until you pulled the block apart and revove the pistons.

    Go with a 6.2. They are easier, cheaper and you have more of them for spare parts.

    As for the core support... don't need to change it for the diesel. Just take a diesel radiator and have the tanks put on the 454 version of the 4 core radiator for a 73-80 body. Then the 454 radiator shroud is a perfect fit with the 6.2. :D

    Next best part about that... the brand new shroud from LMC cost me about $20. I think the upper bracket was around $15 or so...

    Just don't drill any holes in the core support with the radiator still in it no matter how careful you think you can be :doah:
