technical information for a D5N D6 Hemi motor

I need the engine Service Manual for a 1977 dodge D5N truck please
I need to rebuild my motor can't find or buy a Service Manual
thank you eddie

G'day Eddie any valiant service manual that covers the hemi engine will give you all the data you need for the engine except maybe valve spring tensions/height I might have that out at the farm but won't be there for a while
