    All CUCV's came with cast iron exhaust manifolds, what your looking at there is a motor out of a HMMWV (humvee).

    My guess is those headers won't clear the frame rails of a C/K truck /forums/images/graemlins/thinking.gif

    I have them on my M1009 and it only required the exshaust guys to make a few bends in the start of the system

    but as u2slow said, will they fit my 82 GMC K1500. I got a hole in the left side manifold and I want to fix it. I found finding a good manifold in my area is very difficult. and I would like to have a little bit bigger.

    Is it an actual hole or just a leak?

    A hole big enough to put my thumb in. I had an injector go bad and overload the cylinder and burn through the manifold(or so I was told)

    I got another Question about the above motor. would the intake off of this be any better than a j code intake?

    Not enough over the J code intake to notice.

    A M1009 is a military model Blazer the only thing really different is the glowplug system. When I talked to the exhaust guy that put them on I asked him if it was much trouble and he said nope just a little extra bend at the start.

    As far swaping from a j code alot of guys over at the diesel page think the switch is the first step to getting performance out of a six.2 (damn number key on the office computer wont work)

    Hey devil dog I got your heads boxed up and ready to go.

    Just a couple of spotter notes for the HMMWV motors:
    The fuel solenoid, HPCA connectors are the Military style rubber barrel plug. The intake manifold also sits alittle lower than a "J" type. The "distributor" drive isn't a vacume pump but a speed sensor (for diagnostic testing). The TH400 doesn't use vacume for downshifting so no vacume throttle switch either. The fuel feed pump inlet also points a different way.

    There's probably a bunch of other small other differences that I forgot about /forums/images/graemlins/smirk.gif
