Still playing around with the layout of the firewall and trying to determine how much room I will have back there. I took the box surrounding the engine off and tried to get a better idea of how close the engine mount clearances would be and although the engine shipping cushion is interfering with the mount a bit at the bottom, I am able to see approximately what I will be dealing with. The Lord/Barry mounts will be in between the engine and the engine mount, but I am not exactly sure how much distance that will take.
A lot of head scratching in this build section. I tried to take some estimated measurements but in the end, I still don't know exactly, but I do know it will be close back there.
