Being a CUCV means that the fuel solenoid, HPCA, fast idle, & glow plugs were 12V (as opposed to the HMMWVs 24V). Alot of the CUCV glow plugs were (are) crap, plan on replacing them.
If you knew it's lineage it would be easier to decide. I've seen M1009s (blazer) with lots of hard miles on them. On the same note, right now I have SIX M1031 Contact Maintenance Trucks(built 1986), in my motor pool, each with less than 7500 miles on them! /forums/images/graemlins/laugh.gif
CUCVs were procured from '84-87 (AFAIK) mostly 85-86. So the lack some of the block improvements of the later years. The good news is the CUCV was never subject to the Army's Oil analysis program so it got regular oil changes. HMMWVs must wait for the OK from the oil lab before it's changed. (And I don't believe much the oil lab says /forums/images/graemlins/mad.gif
Assuming $400-$500 for a TH400, another $200 for a NP208 (maybe somebody wants one), that still leaves $1800 for the motor; alittle steep - sight unseen. Are there any warranty/garantees? Sure would help if you could pull a head off. /forums/images/graemlins/smirk.gif
