Lets talk about what you want to see in a Gen III aftermarket Block?

That makes a lot of sense. Depending on how the patterns layout, maybe offer it as an either or both option in case someone wants the option down the road (start with a 727 but swap to a GM trans later).

And I would guess that it wouldn't just be racers that would want that. Seems like the 4L60/65/80 is a pretty popular trans, or even the 200R4, so I could see it being a popular option for an G3/4L65E. Unless the 8HP70 because easier to swap.

Honestly, if I were to start a new build that was a cruiser, I'd use the 4L80 trans with a G3. The 4L80 is easy to control with a Holley, and you don't have to deal with all the silly nuances the modern Chrysler transmissions have. The biggest ones being you have to use the factory shifter and then there's only 1 company that supports the control system from a stand alone prospective. Let's not forget the aftermarket support for the 4L80.
