will an OD unit take it

oops also forgot to ask, "how can i tell if this was a slant six unit or a v8 unit??

There is no difference, it's only the bell housing, flywheel and clutch that would be different between a \6 and v8. The bell housing will have the starter location at 10 o'clock verse 7 o'clock on a v8
