oil pressure spring would be a disadvantage. Thay claim that the oil would be
slung
around too fast, causing it to miss some critical points that need lubrication.
In a
full race engine, they claim that this spring is OK, since the rest of the
block is
built up also. FWIW, they shimmed the cap of mine with a small piece of
aluminum
that raised the pressure to 60psi from 50. I guess that's OK, though!?!
