    I was bored tonight and was going through my 5 years of offroad magazines and found an article on all the different t-cases. Well obviously it said you could make a doubler out of the 203 and 205, but it also said you could make it out of a 208--Is this true, and if so how can you do it, and is it worth it?thanks

    You can, but it isn't recommended for strength reasons. Remember, with the doubler you are effectively doubling the tourque put to the second transfer case. Any t'case that bolts to a TH350/400 you should be able to make a doubler out of, as I understand it. But why would you want to? The only reasons I could think of were a variety of low ranges and reduced weight. The weight is no big deal, but having 3 low ranges (~2, 2.73, ~5.46) would be useful, but minimally. I think 4:1 is enough for most fullsizes. Think of the numbers:

    Manual
    7(tranny)*4(doubler)*4.56(axle) = ~126:1
    7*5.46*4.56 = ~175:1

    Auto
    3*4*4.56 = ~56:1
    3*5.46*4.56 = ~75:1

    Those are for an SM420 and 700R4. The TH350 is 2.5 and the SM465 is ~6.7, I think. The 4:1 is plenty low enough for me. If you were really serious about ssllllloooowwww range, you would get a 203/Atlas 2 doubler. 2:1, 4.3:1, 8.6(!):1. That would be the ultimate setup. But at $3500-$4000 on this alone, that is some serious dough. Damn it. You just added $4000 on to my dream blazer setup. I guess I'll push it back another decade :).
