I guess that I was not aware that the tech section now had a comment section. Sorry I missed answering all those previous posts!

Jose, A lot of people are getting their NV3550s from other sources these days and just getting the adapter kit from AA. But I also gather that there is an alternate clone of NV3550 that is now being offered….but I forgot who is doing that. It’s buried somewhere in the CB forums though, that I know. The J**P Liberty and some Dodges of 2000 vintage used the NV3550. A quick internet search ought to find a bunch of sources.

The question about the strength of the NV3550 comes up repeatedly. There has been a lot of discussion, but the bottom line is that the weight/torque numbers outlined above speak for themselves. Unless your Bronco has gained about twice the weight of a typical Bronco and you are pounding out way more torque, the NV3550 is fine. A 351 is no problem.

I’m currently in the phase of putting parts back on this NV3550 conversion. Given the fact that I had no idea what a ’spud shaft’ was until recently, the install and the kit are really good. The instructions bite for a newbie like me though – they tell you to do things like ‘remove the pilot bushing and replace it with the one provided’. They fail to tell you (a) where the pilot bushing is and (b) what is involved in removing it. They also fail to tell you how hard it is to remove the flywheel bolts, which happens to be impossible with a regular wrench but my lowly cordless Makita impact wrench had no problems. This leads to lots of delays to google for answers (by the way, I highly recommend the grease and socket method for the pilot bushing!).

All said, I spent two days on the 1″ body lift (largly due to some rear-end damage that the previous owner had hidden). After that, it’s about a day to get the old parts out, a day to reassemble the spud-shaft/tranny/transfer case. I probably have one day left to re-install everything (new flywheel and clutch are already in), provided I don’t find too many other things to fix along the way (replacing header gaskets, cleaning greasy parts, rebuilding drive shafts, etc.). It’s hard not to do more though, since by the time you have the bellhousing and tranny out you want to do as much as you can while you’re down there.

Hope this helps…

Larry, how many hours (weekends) do you estimate it would take to complete the NV 3550 conversion?

Just a ballpark would help with our planning.

Thanks
