ZF6 swap questions
Haven’t found much in the way of a build thread on doing this swap but I know there’s a few out there that have done it and I get the gist of it all. I’ve located a 4x4 ZF6-750 in the area I’m hoping to pick up in the next few days then start amassing the rest of the parts.
My main question is about the transfer case. I see most people put a np271 manual shift in behind the ZF6 but I’m not having luck finding one for a decent price, the ones I’ve been finding are more than I’ll be getting the trans for. Question is, I know the np271 is a common drop in mod to throw in behind the nv4500, so I should be able to just use the np241,with extended linkage, I already have to put behind the ZF6 correct? Input size/splines and mounting pattern should be the same right? I know the 271 is stronger but if I can hold off on finding one cheaper than the $1400 going rate I will.
Rest of the parts list needed to order so far:
- conversion flywheel and clutch (Southbend)
- conversion hydraulics (Southbend)
- adapter plate (wild horse Mfg)
- 6.0L ford starter
- modify driveshafts
- modify or fabricate trans crossmember
- oil cooler system for trans
If anyone else who’s done this has suggestions on the crossmember and cooling system please chime in.
