It's possible...  however:

...why would you want a high volume oil pump in a street driven car 
that's not going to be revved high enough to demand a lot of flow 
with large clearances etc ( aka "loose" )?

Unless you're going to be buzzing the engine to the stratosphere ( 
and it's put together with "race" clearances ) it shouldn't need a 
high volume pump in any event.   It's gonna do little other than put 
a higher load on the pump itself and add potential wear to the crank 
drive gear... or spill a lot of oil past the pressure relief valve 
(NOT to be confused with the bypass valve ).

After all... that engine has lived its entire 47-year lifespan so far 
without one and it never spun a bearing.     ( at least up until the 
time it left this area) ;)



...gonna go racing?   If so, and you use the HV pump, block off the 
bypass valve.   JB-Weld a coin over the hole.
