there isnt much wiring needed to run these engines - prob about 4 wires or something.
you can use your existing rad/fans and some hoses too. I would try and stick with the MT75 box you have already as used on the twincam as they are stronger than the type 9, just need the appropriate bellhousing and input shaft as stated already.
Rev counter will need modding too as that wont work unless you graft the one from the granada into your instrument cluster.
Prop will more than likely be the same as the twincam too
