tectafab, I am asumeing you have done this swap.

I have a 4.3 I want put in my forunner.  I want to use a chevy auto (th350 or 700r4).  The question is what did you do for a T-case?  Go with a chevy case or dana or stay toy?

I would like to stay toy and keep my twins. but the adapter for that is $$$$.

Just wanted to see what some options are.

Thanks

get the adapter.


i got lucky and it came with it.

i think they are from 199  to 299 ?

Where did you find them for that price?  The only ones I have found so far are 500 and up.

oh    when you said twins   you were talking about sticks?\

i thought you were talking about dual toy cases and the adapter for that.

so sorry.

No, I have dual toy cases and would like to keep them but the adapter to go from a th350 to a toy case is pricey.

same as the 4.3 ?

i got one in my dual case deal  with dave parks ,
thats a big reason im going with the 4.3

how much are they?

Are you using a 4.3 with a TH350 trans to dual toy cases?

This is the setup I would like to run.

What spline is your toy case and did your adapter to go from the auto to toy csae require you to change the output shaft in the trans or just bolt up?

The only adapter I can find to go from a TH350 trans to a toy case is from Downey an it is $500 plus and you have to have the output shaft on your trans swapped out.

Thanks for all your help flea.  If you were closer I would come check out your rig and lend a hand.

thats what ive got    ill check on your other ?   
i bought the cases and adapter from a friend that moved to great bend.

ill see if i can get ahold of him and ask him.


im good a taking advice and copying others ideas so i dont know a couple things ! 


thanks for the offer

im trying like hell to get this done this summer   

Flea,

I may have found a cheaper solution.  NP231/241 T-case froma chevy.  I can find a trans (w/ overdrive - 700r4) with case for less than $300 rebuild trans and T-case with 4-1 for a few $$$ and still be less money than above mentioned setup.  Plus a NP231/241 is really common so parts should be nothing to find.  I think this is the path I will be going.

that is a great setup and has alot of aftermarket support so less $$$.

anything special youll do to the tranny?

I will have it rebuilt by a good shop with all the corvet servos and crap put in it to make it last.

The shop I take my trans to has about six lifted Heeps of all ages with 35 plus tire sizes and they are all running overdrive chevy trans with 4.3 or small block power in front so I am not worried.

little late to jump in here
with all that i have done i have used AA
th350 to toy case 21 spline
i might be wrong but i was thinking $350 bucks ??
or you can run the toy 5 speed with a bell housing swap
