Good find on the pics! Yes, the 8 speed is huge. There is a guy on Facebook putting one in a car...let me see if I can find the info for you.

Joel Applegate is his name. He frequents the page G3 Hemi Swap. Here is a picture of his swap, but doesnt show you much. There are two sizes of the 8 speed, the "90" and the "70". The "70" is smaller but doesn't handle as much hp.
