Its not going to be much heavier than any other FJ40 with a V8 and one ton running gear.
The 6.2 and 6.5 weight and size are between a 350 and 454.
Thanks guys for all the input, keep it coming, gets everone and me thinking of everything that I need to for this conversion.

I am all for the one ton heavy metal running gear but what is the advantage of a 6.5 over a 350? I have never heard anybody say anything good about a GM diesel before the Duramax exept how the 6.2 sounds with a straight pipe (which is also questionable). The most negative talk I hear about those motors comes from the fleet mechanics that work on them. One guy in my club has a 6.5 equipped dually and gets outpulled by guys with gas motors. True, it may not weigh that much more but you will actually have some performance with the gas motor not to mention the most heavily supported aftermarket parts supply in history. The only merit I can see is the luggability of the diesel for crawling. How simple is it to hook up a 6.5? Is there much support hardware you will need to run it like a intercooler or anything? Whatever you decide to do I am excited to see the photos. From my experience the people who love the 6.2 are the die hard chevy guys that would tell you their fullsize chevy truck is the best ever period, even if it had an Iron Duke 4 cylinder in it. Well maybe those guys are just isolated to the population of MN farm boys.
