Small block mounts 4x4
Hey all!
Does anyone know if the stock engine crossmember and the motor mounts will work with a big block? I am getting conflicting info, some have said that you can use the original small block motor mounts and crossmember to mount a 396, others have said you need to use a 73-87 crossmember with small block mounts to put a big block in a 4x4. I am building a 72 GMC 4x4 and the previous owner installed a 455 Olds motor in it and cut out and threw away the original. I have access to get an original crossmember with the small block mounts but don't want to get something I cant use. Anyone have any thoughts? Thanks in advance.
