Does anyone know!

DOes anyone know if the manual shifting Blazer is worth more than a Automatic?

ALso I wanted to know if I have A manual shifting Blazer with the Compound Granny gear box in it...........What would it take to make it a automatic?

DOes anyone know what I have to do to the transfer case to have it bolt up to a turbo 350 trans? Or what I need to get? I already have a tilt Automatic steering. Just need to know what else I need to get?

Re: Does anyone know!

The transfer case needs a different size bearing IIRC,atleast one of them.New adapter plate,which costs around $150 and the splines are different between a manual tranny and a th350 so some work will need to be done

The bearing is the same for a 10 spline (SM465) and 27 spline (TH350) input on an NP205. The input shaft is different, obviously. The bigger bearing is required to install a 32 spline female input like is used with a TH400.

To do this conversion, you do need the correct adapter and drive sleeve for TH350 to NP205 as well as the correct input shaft installed in the 205. It is usually cheaper and easier to find a complete TH350 with the 205 attached and just sell your SM465/205 as a unit.

Re: Does anyone know!

I found this here awhile back.If you read this,it will answer some questions
Quote:
205 Input Trans
10 spline male SM465 4 speed
27 spline male TH350 Auto
32 spline female, (short) TH400
32 spline female, (long) Later model 4 speed? (Not sure if these are still the SM465 and the "long" female input may have also been behind some TH400 transmissions? Not to familiar with the "long" input.

Here's some more;
the 10 spline and 27 spline male input 205's use a smaller input bearing than the 32 spline female input.
So, for example, if you were going to run a 4 speed, (10 spline), or a TH350 trans, (27 spline), the 32 spline input 205 cannot be used. You can't change the input to the smaller bearing inputs because the hole in the case for the bearing is to big.
Now on the other hand, if you were to go the other way around, you can always have the smaller bearing hole machined out to fit the larger input bearing.

Re: Does anyone know!

as far as $ value, an auto is probably worth more. As far as off-road capability, many prefer a 4 speed manual. Three on the tree is definately worth the least, mostly because many people don't know how to drive them. What ever came factory is probably worth more than a swap if you're going for a resto. If you're going for driveablity, do what ever you want, it's worth more to you if it is built how you want it.
