i have an opportunity to buy a military pull out with 30,000 miles on it for no more than 500 bucks. that bein said the oil cooler lines on my 6.5 went bad and in turn spun a bearing or something that caused a lot havoc in the bottom end of it.:nonod: problem is i live in tennesse , i am in college in mississippi for john deere and i am driving a volvo wagon :mad2: good thing is the motor is down here close to where i am. would this motor be a good drop in as it sits or what would i have to do to get the gauges to work as im sure they wouldnt being an older motor.
 
you couldn't do it as a drop in. however it doesn't take a whole lot to make it work. all the parts between the 2 are interchangeable. the IP and lines have to be done as a set. if you take heads, intake, turbo and exhaust manifolds you can use them with the 6.2 block. IIRC you have to change the timing cover off the 6.5(for the crank sensor). I know there's another part under the timing cover that you need. I can't remember the name of it.
 
Reluctor. It's got the four tangs. I think it's called reluctor.... :dunno:

Depending on the year of the 6.2, you'll need a longer turbo oil line and a fitting to tap into the Oil Pressure Sender fitting. Then a longer turbo oil line to reach. (36") Newer 6.2's have the same turbo oil location as the 6.5.. Same block for that matter. (bore difference)
 
Is the 6.2 guaranteed for x days and you have seen it run? Or is this a standard unknown take out engine that could be full of sand/cracks/etc? The 6.2's can be had for double the price, tested, and have a short warranty. Myself I hate to pull a bad engine back out. I have looked at enough bad non-running 6.2/6.5 engines including one that the intake was full of rain water.

The military pull outs should have the cylinders deglazed and new rings put in. IMO they don't get run hard enough to seat the 2nd ring and when you get it is it too late to get it to seat/break it in.

You 6.5 swap is missing one critical part, the turbo! No oil to where you lost the bottom end also means the turbo bearings are unfit for further service. The oil cooler is also suspect depending on what reached it with the last gasps of oil. You can find a cheap GM3 or 4 around depending on your budget. Or get something better. Maybe a little exhaust work and go NA.

Your tuner can help you use the DB2 on the 6.2 with what you have.

You can use most of the 6.2 including the heads. I would recommend using 6.5 precups NA or turbo as the 6.2 precups limit you and smoke like a freight train in a tractor pull.
 
warwagon the turbo still spins freely but im not sure to trust it this motor isnt goin anywhere anytime soon and i havent even seen it yet i just wanted some opinions on what it would it would take to swap out or if it was even worth it
