Thanks for your update! At close to $7k to get same for my '99 100-Series ... it just didn't pencil. But excited to see you are pushing forward with the FF Diamond! Did you go D60 outers?

Any more recent pics? I love this thing. I have an 81 chinook I am about to tear into.
So I have not made any changes to the Tunook since I got the new rear axle under it. I am still fidgeting with the emergency break but other than that it is working great.
I am currently considering a trd supercharger for it. I already have the supercharger and was able to remove it from the previous vehicle, so I know that I have everything to install it. The only concern I have in doing this is that the Tunook has 177,XXX miles on it. I am wondering how it will hold up. I would be interested in knowing if anyone has or knows someone who installed an SC on a high mileage engine and how it worked out? My reason for doing this is to add a little more torque and HP. I am looking for a little extra of each and not push anything near it's limits probably stay around 5-6 psi boost.
The 4.7 does great on the highway, holds 80mph no problem, and forest roads are no issue. I tried to drive over Elwood pass last year though an stopped on a steep section of the trail to scout it. I found the 4.7 just couldn't haul the Tunook up the steep slope after stopping it wouldn't go up. Getting a running start may have worked but I didn't want to tear anything up trying that. So I am hoping the SC would add some low end torque to help in those kind of situations. I also re-geared since then from 3.90 to 4.11 gears. Not a big change but a little better.
My only experience with superchargers is in my 01 Tacoma, I have a 3.4 with an SC and it has 278,XXX on it, it is doing great. I got that truck at 165,XXX miles with the SC installed. I don't know when it was installed though.
Any thoughts?
I don't have any experience with the 4.7, but I would say as long as the motor is in good shape, strong compression etc, then you should be ok. I put a supercharger on my 3.4l at ~250k and it handled it fine.
If your worried just add a AFR gauge so you can monitor it and back off if things start leaning out.
Also what size tires are you running and what does it weigh? What are your RPMs at ~80? I know you've already regeared but maybe going to the 4.30s would be more help too.
