I'm in the process of doing ZD30 Auto to TD42 conversion, Im using zd30 auto and bellhousing, is there any reason I cant just run the zd30 starter motor instead of drilling and tapping out the bellhousing to suit a td42 starter? Can the zd30 radiator be used ? I have read it cant but noone can confirm to me why?

I'm using the original zd30 radiator on my 4.2 conversion. Shroud fits. Just need to plumb the reservoir in.
I haven't given it a hard workout yet but all seems good.

Did you have to change the cap to a pressurized type ?

I'm still using the zd30 expansion tank, its plumbed back into the housing for the lower radiator hose. Radiator caps haven't been touched.
