Default ZF6 swap spin-off

Do the Camaros & Firebirds w/LT1's & 6speeds use the same ZF6 as our Corvettes?
If yes, can these be used as donors for us?
What about their rearends... Do they run dana 44's? Are these interchangeable as well?
Thanks

the camaros and t/a's use a t-56 trans, also they do not have an independent rear end, they still have live axles.

They're different beasts-Sure the swap can be done, but it sounds a lot less troublesome to stick with the ZF

Not trying to start a war, but the ZF-6 was offered in a/some TA's as I recall. Although I think they're proabally pretty hard to find and would cost just as much either way.

Most of the ones you'll come across will have the t-56

You might be right...I think the first batch of Firehawks that SLP produced used the ZF-6 from the Corvette. These were very limited production so I doubt you'll find one at your local wrecking yard.

That is correct. I think it was 25. And the motor was a 350hp screamer. These cars are going to be worth 6 figures in no time. More details:

SLP Firehawk Specs
Apparently, there were 27 ordered, 2 were cancelled.

The downside to the ZF6 was cost, and the shifter didn't fit right, so SLP had to some serious modifications to make it work.

The T56 CAN be made to fit the vette, but it requires a special bracket to mount the C-beam up.

Kiesler is selling the TKO, which is a T56 based 6spd for the C4, and it's a full blown drop in. But I don't know if they have a kit for the ZF6 conversion (it's about $3000.00 for their kit - a good deal, really).

They are also doing a 5spd conversion...

My feelings on transmission conversion:

If you are going from auto to manual:

1) ZF6 (this is the best option, really)
2) Kiesler (the 5spd doesn't require cutting, cost effective)
3) T56 (A lot of custom work)

From auto to auto for drag
1) TH350
2) TH400
3) Either with a Gear Vendors overdrive

From manual to manual:
1) Kiesler (the 5spd is a great choice to replace the 4+3)
2) ZF6
3) T56

I've got more than that so far into my ZF6 conversion and at the end of the day I've got a used tranny. If I had it to do all over again, I would have gone with the TKO-600. If I manage to kill this ZF6, I can guarantee a TKO will be taking its' place.

Thanks y'all
It looks like a TKO will be the ticket, but thats noy for a while now. Will I still need the steering column from a manually equipped car? Is there a parts list of what's needed to complete the swap?

I actually called them and asked them if this trans would fit in a ZF6 car and they said they didn't know.. acted totally ignorant.... I said "well, if I use a bell housing from a 4+3 set up it should work... right?" uhhhhh. "we don't know". I think it would absolutely work and that's the route I'll go after I kill the ZF6 I already have.

not really... it's just that the Richmond is rather old school... external linkages, things like that.

Also, the internals are not all that well made, from what I understand.
