I want to see how you plan to route the exhaust to the turbo with how tight those frame rails are. Snaking both exhaust banks to one side won't leave that much room in my mind. Maybe the bay looks bigger once the straight six is yanked out of there. That's the reason I want to supercharge it instead.haha ive got a ton of ideas but not enough money to back them up. I measured everything out when i installed my LS and there is plenty of room for a turbo on the passenger side with a wastegate that will share the exhaust outlet. Theres also room between the frame rail for a 3 inch (maybe 3.5) exhaust pipe to run out the back. This way you can still run a Cat, resonator, and muffler. With the E-fan theres a ton of room as well to route the exhaust in front of the motor for the hot side of the turbo, and even some room to maybe space the radiator and condenser back some to put the intercooler behind the grill! Its also looking like the holley LS Swap manifolds will work for the turbo hot side, just flip them backwards.
