    Hey everyone, I've got a 1979 Camaro Berlinetta. I'll give you all a list of what is currently installed on the car.

    The Original TH350 with some sort of shift kit.

    A Chevy 350 with a mild-ish cam, Edelbrock RPM Dual Plane Intake, Edelbrock 650 Carb, and Dart Iron Eagle SS heads.

    Original 10 bolt with an open diff and I think it has 2.73 gears (which I plan on changing to a posi and 3.42-3.55s)

    The TH350 shifts nice and feels good, but I wanted a manual for fun and fuel economy (it is my daily driver and I make a long trip to work and school.)

    The end goal of this build is a comfortable daily driver that I can have some fun with. I was wondering if anyone on here has done it and if it is worth the effort.

    I found a T56 out of a 2006 Corvette for a super good price, but he says it needs to be rebuilt. I am willing to rebuild it myself or have it rebuilt if it is really bad.

    I've read that you can use a T56 with older SBC's with an expensive flywheel, but I wanted some confirmation on that.

    Basically, I need to know everything I'll need to do (or if it's even a reasonable thing to try) or buy to finish this swap. I don't know if that is too much to ask for, but any help would be immensely appreciated.

    My budget is tight, but I plan on doing basically all of the work that I can.

    Thanks Guys,

    That trans will not work at least without more parts. I think the tail housing and tail shaft have to be changed. I'll let others connect on that

    In general, what has to be done to put a t56 depends in what t56 - there are a lot of variations.

    Also in most cases you'll really want a 3.73 or higher rear gear.

    Yea, I'm having a hard time finding specifics about putting the 2006 Corvette T56 I've found into 2nd gens. I've heard the LT1 T56s are an easier swap, but still not a piece of cake. Thanks for your reply!

    After reading the original thread starter, you cannot use a late model T-56 it must be one out of a Camaro or Firebird to work.
