The E4OD's antics are getting to me, so I was doing some thinkin (uh oh). I cant afford a ZF and I dont trust the M5OD, so I started looking at the older 4spd sticks. Right now I have 3.55 gears and 35" tires, so it's sluggish, but one thing they do for me is give a huge overdrive on the highway. For a 1:1 stick, that means I'd run 2600 RPM in 4th gear at 75mph, which aint bad at all since I need the revs a little higher than stock to push this beast anyway. As for taking off, the 6.69 ought to be plenty as my effective 1st gear right now on the E4OD with convertor slip is less than 4! Hell, I could even step up to 38's and be better off than I am now! Yes, enter excitement.
If I swapped in a 1 ton rear with 4.10 gears and matching front pig, I could probably even run 40's without having to swap gears, which would be very very sweet. This puts more load on the driveshafts but I'll have to have them changed anyway, so I'll step up to 1350 stuff while I'm under there. Also, since I'm playing with old iron, I figure I might as well stick an np208 under there with a real stick and get rid of my leaky electronic case, though she's been good to me over the last couple years. I know that combo will be significantly shorter than what I have now, maybe even enough to fit a 203 doubler box under there?
Anyway, I mainly want to know what you guys think of this plan, and see if I'm missing something critical. My brother had the sm465 granny in his blazer with 35's and 3.73s and he didnt even bother with the low because he didn't need it, so I figure I'm good to go, even for 38's. This seems almost too good to be true because now I dont have to deal with this damn automatic plus I can avoid the $1200 for changing gears that I'll never actually save up anyway.
1) To NP435 guys: what clutch do you advise and what's the deal with 10" vs 11"? Dont I want the biggest I can fit?
2) What should I do with the E4OD and BW1356 when I'm done? I figure I can probably break even by selling that stuff.
3) What is a good price for a 435 or 208 and should I rebuild them before install?
4) What kind of connections does the 208 use for the driveshafts?
5) How hard will it be to put mechanical linkage in a 93 Bronco that (i think) was only available with hydro linkage?
I did try to search some of this but unfortunately Steve83 used to have "np435" in his sig and he used to be Sir PostALot, so the search gets useless pretty fast [img]images/graemlins/chairfall.gif[/img]
