SWEET!!!

I'm subscribing! I am doing an LS1/T56 C4 also (though no turbos ).

Do you have the hydraulics for the T56 worked out? If so what line and master did you use?

Am I misinterpreting the pics, or is there no room for a radiator?

Anyway, I dig it!!

Thanks,
I'll be using the stock clutch master and conecting that line to the stock line for the t56 I'll cut and flare the ends and put them together. the radiator will fit behind the intercooler im using a scirocco style radiator its pretty small 22"w x 13h

This is exactly what I did Looks like your swap is going well. What are you doing for the gauge cluster? Keeping it stock, using aftermarket? I ended up (still in the process of finishing) putting a C5 corvette dash and interior in my 84 with an LS1 T56 combo. I just can't wiat to be finished with this damn thing... nothing like a 3 year project. lol

For gauges I'm just going to use autometer, the stock cluster is burned out anyway

I'm sure I could find this if I researched it, but I've got a few questions:

How did you come up with the torque arm mount on the T56?

Is that the stock Dana 44 torque arm?

How is the shifter placement of the T56 if you are using the stock torque arm?

Nice build man, I'd love to stick an LSX in my, I just don't have the nerve, lol.

I made a custom mount that bolts to the back of the t-56 to mount to the stock torque arm.. the shifter is centered in the console now...

How well does the shifter line up with the factory consol? As a fromer C4 and C5 owner I love the swap.

Thanks,
It doesn't line up at all it's centered between and just in front of the window switches...
