They might be the oversize "Z" valves. How big are they? Off the top of
my head I don't remember if the stem diameter and length were the same
for the L-series motors and the U-20, but I'd be more surprised if they
were different.
I'll look in the M/S catalog and some other books this evening at the
house. We'll be running 4.38 gears in the E/P car and 4.11's in the
street car, both with 5-speeds. It's really amazing to see the real world
differences that come from a (relatively) easy diff. ratio change. Easier
on the 510 and Z than on the solid axle cars. Remember you get similar
results with shorter tires, too. We ran 20 x 8 x 13 Goodyear slicks on
the 510 in Hawaii in the early '70's and the difference in diameter
(compared to a taller street tire) had a BIG effect.
I'm building my (actually our) own E-Ticket ride! <G>
Later, Ron
