Hey guys

Thanks for the feedback. I'm still stumped with this, but I've got a funny feeling its for a 4x4 or a Ford gearbox as suggested above. The starter motor location must be a clue but cant figure it out yet. I cant find any conclusive results on Google so still looking.

BTW, the 308 engine block in the pictures is one i had bored to 60 thou over and made ready for a stand, but after smoothing it out and applying a clear coat, it somehow got rust under the clear coat so ended up looking terrible in the pictures.
