I have the Gen IV 454 and a TH400. It came out of a 90 or 91 truck. Other than frame mounts needing to be moved. What other issues do i face? Will the Oil pan clear or do i need a new one? I assume i have to have another set of headers as well? OH to add the engine is complete with all the accessories as well. Any input would be greatly appreciated.
