I am doing an LT1/TH400 swap and need an adapter, whatcha got?

*edit* Dammit, it's a TH400, sorry.

i can get you a new one from AA for a decent price......

 

[ScottFJ40]

Cool, how much?

 

[orangefj45]

need more info first.


2wd or 4wd th350?

10 or 16 spline t-case?

 

[ScottFJ40]

Pretty sure it's a 4wd th350.

I have an original 1978 tc, not sure what spline count that is?

 

[orangefj45]

it's easy to tell if the th350 is 2wd or 4wd. the 4wd output shaft only pertrudes about 1" from the back of the trans case.

a 78 cruiser t-case is definetly a 16 spline unit.

so you'll need this kit:

i'll send you a pm with pricing.

Thanks man!

 

[orangefj45]

sorry, computer went down for a minute. sending pm now.....

note: the AA adapter does require you to replace the transmission output shaft with one they supply in order to mate it to the t-case.

Thanks!

It's a th400(4wd) sorry about that.
