. This guy has a hooker manifold on the driver side. He has a trailblazer manifold on the passenger side. I do not believe he has the driveline angles even close to correct. It looks engine is in with no transmission
Looks to me if he had the engine properly located a hooker manifold on the passenger side he could move the engine over more to passenger side and gain clearance around the steering.
