Hi retro ford sell engine mounts or you can buy a kit you weld yourself
the inlet manifold can be replaced for different carbs twin 40 webers or a twin dgav
sump is most likely for a front wheel drive , I think a 1.8 cvh sump fits for rear drive,
the ignition , (sparks for engine) a ford 1.3 hcs edis unit will work, if you need low cost,
or other management systems are available / emerald/ megasquirt/ megajolt/ weber alpha/ there are many more
exhaust manifold can be brought for a rear drive, or you can cut and modify yours,
or possibly use complete, easy to work out when engine is in
coil pack may need relocating, it is possible to run the engine as it is, if you can fit wiring loom and ecu from a /focus / esocrt /or mondeo
there is perhaps more help if you use "search" on old topics on here,
and google search will find a website "zetecinside" flywheel from 1.8 zetec engine or a 1.6 cvh efi (the one that uses a coil pack) 1.8cvh engine may have coil pack if so you can, the sparking system and trigger wheel, plus the sump as mentioned earlier
great looking shell, keep us posted with pics , good luck,
