Unfortunately, you have to remove everything from the rearend to swap gears.....brakes, half shafts, and even remove the center section from the car.

I think I would give myself two options in this scenario:

1. If the engine is still in short block form, then I would swap to a smaller camshaft. A cam swap would be super easy if the front of the engine isn't buttoned up, heads are not on, etc. Also, you can still have a very nice sounding, lopey camshaft without having a wild, temperamental camshaft. You could cut the duration down some and help with the low/mid range manners while still having a thumpy sounding engine.

2. Run everything as is and just see how you like it. You could always swap parts later down the road.

I would still go with the TKO 600 and the .82 overdrive....and picking a suitable clutch kit is simple.
