Thread: 4.6 in my disco

If you mean Disco1 then you will need to change the cam, front cover, inlet manifold and injectors, then remove a dowel from the front of the block and the end of the crank (or drill your old flywheel/auto drive adaptor to suit). You will also need a spacer ring to allow your front pulley to bolt up tight as the crankshaft nose is longer. The heads may need some hole threads altered depending on your model of D1, or reuse the D1 heads.
