BB and modern 8 speed Auto transmission ?

My Hellcat has only 6 gears, as any gentleman's would. lol

I believe the Sprinter does use the same basic 8 speed as many other cars including the Hellcats.

Using an 8 speed with 3.23 gears...that's OK but you're transferring the multiplication from the rear end to the trans. Which is better able to handle the torque of a big block with lots of traction?

Keep in mind most of today's engines - even the Hellcat's - are not super torquey down low.

It'd be cool, for sure, but I'm not convinced you'd actually get anything out of the first 2 or 3 gears on the strip.
