the duration gain (if you're going to even call it a gain) would be the
minute increase in time require for the valve to fully open/close. Since
the valve must travel farther with the 1.7s, it's going to take a hair
longer to open/close.. The cost/hp gain ratio is quite low for RR's, IMHO
one should mod the greasy snot out of the motor before worryin about RRs.

Ok, feel free to kick me in the nuts if I'm wrong, but 1.7's don't
increase the duration. They increase lift for sure, but I don't see
any way they could increase the duration of a cam. Come to think of
it, I don't see any way to change duration at all without changing the cam.
Am I right or wrong?
