1967ChevyTruck

Hello guys I am new here and want to help and get info on the LS2 GENIII takeouts installing them in Older GM make vehicles. I am currently installing the 2006 LS2 truck motor with a 2005 GTO tranny into my 1950 Mercury with a 1978 Camaro front subframe. I am having issues with the power steering, AC bracket and the Steering linkage hitting the oil pan. As well as the Manifolds hitting. Yes I know go headers. I just need some guidance. Thanks in Advance.
