what to do with the six

Mouse
Too much stress on the cam gear. ALL replacement oil pumps are higher volume than the stock units they replace. The slant does not suffer from any oiling issues thru 5.5K RPM. Oil mods to the block can improve oiling to certain spots for race apps. A hardened gear pump is available from myself and Doug Dutra (zero failures to our knowledge) to address the powdered Iron gear found on the new pumps.
All this is documented well on the slantsix.org web site.
