1953 F100 LS swapped lq9,4l80e 

I used just the stock ls manifolds. Was tight on the passenger side even with those.

Used the factory crown vic ones,then drilled and welded a plate to adapt over to ls.

Hello friend, I am doing something very similar, could you help me with a photo of how you adapted the engine mounts to the suspension, please, greetings from Mexico City, great job.
