I have a 383 I am building and want to hook up a early LT1 T56 to it. What will I need?

It depends on which direction you want to go with the T-56. OE or Aftermarket. OE will mean you'll need a complete T-56 setup including the clutch assembly (make sure it's complete - the T bolt isn't avail from GM anymore). Depending on if your block/crank is pre or post 1986 you could also need a special flywheel. Pre-86 is 2 piece rear main as I'm sure you already know and will require a different flywheel.

If you go aftermarket, you can use a traditional clutch setup, flywheel, etc.

I hope this helps. Let me know if I can answer any LT1 clutch setup questions. I've done a couple of them.

Cya!

Thanks for the info, I am going with OE it has the clutch and everything still I guess I would need to find out what fly wheel I am going to need.

You will need to get the "special" flywheel, you can look it up at Summit.

Thanks for all the help guys.
