or you can build a 6.2 bottom with 6.5 stuff on top, depending what you want to do with it determines how much extra effort/cost you want on the build, My 6.5 is 200+, rwhp & 400+ rwtq and pulls 18K load on occasion, but have done a lot to get there. While not huge numbers to what other engines can do considering 195 flywheel rating from factory 200+ at rear wheel is significant gain. Good buddy of mine with his 6.5 holds the 6.5 world speed record at Bonneville 153+ mph.o properly set up a 6.5 can and does deliver the goods, as far less cost than one might imagine, spare parts are plentiful, due to poor care and feeding they earned a poor reputation, so you can get complete truck with thousands of $$$ of great parts for including good engine & trans for less that what you pay for boneyard salvage engine on considers as "THE" engines for power.
I'm on more sites than you can shake a stick at same handle on all of them, PM me here for more info on tricks & tips for the 6.5.

2 precups for the 6.5 L56 (S VIN) engine is emission has smaller, & close to 6.2s, L65 (F VIN digit 8) is non EGR more fuel & hp from factory has larger cup,
6.2s capable of 24-26 mpg driven conservatively,
13-20 L56 and 3:73 rear depending on speed & load,
L65 10-18 avg with 4:10 rear depending on load/speed

AMG makes the premier 6.5 on the market today will only sell long block but not cheap, has beefier blocks to counter weakness of earlier design.
Peninsular, is top of line for remans, couple of other folks sell a quality reman, if the cost seems low/reasonable on one you find on the net, high probability it has knock off china made parts, not all china stuff is bad, but the variation between good-modertate-bad chinese parts is huge, you had better have a personal relatioship with the retailer of the reman engine to make they will stand behind the bad part that may fall into your lap or their build.
Remember many places buy cheap as they can to keep cost low, culled or inferior parts are in abundance, even in ou US military Mil-Spec. parts supply chains we see that issue from time to time, just as word of caution buyer beware.
