Welp. She has had about 100 miles of test drives and 1 loaded test up over the big flyover here in Memphis. Overall she runs pretty good. Can't complain. Turbo sounds good. I got the jakes wired up, they are just on the high setting only until I have time to mess with it later on. But it does work pretty good and is pretty loud considering the muffler I have.
Loaded is we all knew would be night and day difference. Up over the big flyover here in memphis is about the only steep hill i have and she held 64/2200rpms for the mile from top to bottom with the M322 and a M931A0 on it. Decent was easy and just used the jakes.
I ended up using the NHC250 fan clutch with the smaller diameter fan. The large fan off the 400 was bigger than the radiator so i scratched using it. You really can't hear the fan clutch come on while operating though and I noticed zero loss of power even loaded with it engaged. Temps are staying around 180 degrees. Even with it being 90 outside and running around town. it did not climb at all, even loaded.
I do have some leaking on the oil pan gasket. I am going to try to acquire another oil pan and modify it to give my front drive line a little more clearance and then replace the old pan and gasket at one time.
Least my air conditioner works.
Speed wise 64mph is 2150/2200rpms. Should be fine to run around that empty. loaded I will probably keep it at 2100 or so. The governor is set to 2450 and that is 74mph. I will post some videos of her pulling with a load behind her later on.
Overall though I am happy with the mod. Tired of screaming and yelling at it finally. Not to mention everytime I do one of these mods it tends to be Jul/Aug/Sept in the south. But hey, atleast it isn't the snow preventing work from being done.
