Yep, the factory Exhaust manifold dumps directly over the Bronco Frame on the Driver's side. custom shorty Headers are probably best.
The oil pan fits OK on the Front and clears pretty well over the Front axle. this really depends on how low you mount the Motor.
The Godzilla shares the same modular Bellhousing as the Coyote.
I have taken some measurements of the Godzilla. Length is to the end of the Water Pump. You can find these measurements of each online.
Height, Width, Length
Godzilla - 33, 20.5, 30
351W - 29, 25, 29
Coyote - 28.75, 29, 24.60
The Godzilla, although very tall and long, is Very skinny.
