Dana 60 with upgraded slant six

Dude, an 8 1/4 will do everything you want, has a billion parts available, was built since the dawn of time, and isn't so heavy.
Putting a Dana behind anything less than anything with a trans brake or a BB/Hemi is foolish.

ESPECIALLY in a street car. Ditch the unsprung weight and steer clear of more than you need.

I would agree. Unless there is a higher performance option in the future? The Dana with today's upgraded axles and spool units can handle darn near anything your A-body can throw at it. And even if an over kill for a 225. It will be noticed if sale of car is also in some future scenario.

I believe in over kill. And I would certainly grab an A-body with a Dana before an 8 1/4 - 8 3/4 car. All things being equal.
