Hey guys, search didn't work so well. My question is, where can I get a flywheel that bolts up to a 6.9 engine so I can use my ZF 5 speed? hopefully this is possible---Rob
Yep that 6.9 will do great with that zf5 behind itWill a 6.9 pull a 5th gear?
At about 3 lbs of boost they will pull double overdrive with 3.55 axles attached to 33" tires.Will a 6.9 pull a 5th gear?

Mine is n/a with 3.07 rear gears. Unloaded I never grab 4th for hills of any grade. Anything over 3k on the hitch and she greatly appreciated 4th on anything other than flat ground to keep egts down. Very rarely touch 5th towing over 8k
1983 f350 6.9 zf5 2wd srw single cab long bed. Facet duralift, optima red tops, bfg all terrains, 4" exhaust from y pipe back, autometer z series pyro, pump turned up 2 flats

Mine barely pulls 4th with 3.55 gears and 285-75-16 tires on flat ground. Any hill and I drop to 3rd.
