Today I got the images that compare a T56 with the Dodge 8HP70. This was a collaborative effort between myself, one of my customers, and Domi-Works. The images compare a Dodge 8HP70 with a GTO T-56. The 8HP70 is the gray outline and the T56 in black.
Here is the side view and you can see how the top profiles of the 8HP70 are about the same as a T56. Keep in mind that this will change a little bit with the 1" adapter installed, as the 8HP70 will sit one inch back.
This is the bottom view, and obviously the pan is wide, but the case profile is slim.
You can see that the case is slimmer in this top view.
This is the view from the rear...
The front view shows that the bellhousing overall diameter is about the same. This view also shows how much the 8HP pan extends down. I can tell by looking at this that the 8HP oil pan will be about 1" below a Holley 302-2/3 oil pan, which is very common for GM A-body LS swaps.
and lastly a couple of 3/4 views from two different angles...
I hope these images can help people better understand the fitment requirements. Judging by these pictures, I don't think that I will have to do anything to the tunnel in the Cougar to make this work. It actually looks like the transmissions mounts are very closely aligned.
