Hey guys I'll try and keep this short for you, I have a 92 Yukon gt 4x4 with a tbi 350 and want to swap in a 5.3 engine only and keep my trans. Can anyone tell me what mounts, manifolds, and other parts will help me get this done as simple as possible and hopefully as cheap as possible ? When I had my 85 4x4 suburban and wanted to do this swap I was told I would have to change my front crossmember is that the case with The gmt400 platform or will it drop right in with the right mounts ? Thanks for your help
