weak 6.5 blocks

first make sure it is not cracked already. if it isnt make sure block and rotating assembley is balanced and machined correctly. throw a fluiddampr on there and some evenly pop tested injectors and it should be mostly crack free. I would use main bearing studs too but thats kinda over kill.
There are girdles out there but the only good ones i have seen are custom pieces that no one really wants to reproduce and the girdle on the p400 that the military uses. also block filler is an option but on a street driven truck its kinda hard to use cause you cant fill the coolant passages too high cause it will overheat.

I would do everything woody said but if it was me I would ditch the 506 block you should have in place of a 599 early 6.5 or late 6.2 one with a one piece rear main seal. I would also put a scat crank in it.
I would stay away from girdles most of them are not ridged enough to make a difference. The big problem with the 6.5 breaking mains is they weren't machined accurately enough from the factory.

I keep hearing about the girdle on the military blocks, but I rebuild 6.5s and 6.5 turbos for the USMC (and sometimes Army units) and never came across one with a girdle. Is this a new feature? Where can I find info on them? I rebuilt my last military 6.5 in 2008

well the girdled 6.5s came out in 2009 im pretty sure so thats the reason you probably have never seen them.
just type in p400 6.5 diesel in google and you should get some results
