I needed to install the cradle back into the car in order to verify clearances and visualize potential issues. So far, I like what I see.
Passenger side looking into the engine bay.
It's kind of difficult to see but there is clearance between the driver side frame rail and the end cover of the F23.
Driver side looking at the end of the transaxle.
From the top looking down.
Right side looking down.
You can see how much I moved the driveline as shown by the lower engine mount.
In this current configuration, you can see there is ample room to design a front mount somewhere in this vicinity.
That leaves me with this photo.
I chose to move the engine slightly to the rear therefore I need to be absolutely certain that the rear exhaust manifold will fit.
I don't have a 3800 cylinder head or stock exhaust manifold so I'm partially stuck right now. I will look around for these needed pieces but until then if anyone has a 3800 in their car and would like to help, I'd like a few measurements please.
1) The distance from the edge of the block to the trunk wall as seen from the green lines. Using unmolested 3800 engine mounts in stock location.
2) The distance from the trunk wall to the edge of the exhaust manifold (or header) please specify.
Take a nice, horizontal measurement to retain accuracy.
