    Wow very nicely done looks like a clean swap. How much did this end up costing?

    I would love to have a t-56, but its just way too much money and with a full console it makes it hard to have a good shifter.

    Congrats, really like the look of the truck. Now, post a timeslip or two. What does this truck have for a rear-end? Curious.


    Hope to get mine done soon as well. Mine isn't as complex though, just a 4.8l.

    Because I worked on it myself with alot of help from friends, sold off old motor, sold off some GTO parts, it was hard to keep track of costs.

    The rear is out of a 1990 454SS with an Eaton posi and the stock gears 3.73. I have a set of 4.56 gears that need to be installed.
