As you might no the XA is now a project and ive just started on the body. Im trying to decide on the engine at the moment. 351 Clevo or a 250 cross flow turbo. If i did the turbo engine i would use an XF engine. My XA currently has a 250 pre cross flow in it. What i want to no is will an XF engine drop straght in using the XA engine mounts and will the XA 6 cylinder radaitor be alright? Also will the original Borg Warner tranny in the XA bolt up the the XF enigne in the XA bay?
