>>Frank--you mentioned that 1.7's gave more lift and duration. I understand
the lift, BUT more duration? How is that possible--the cam grind determines
what the duration is --Does the rocker change offset to the cam and make
the valves hold open longer ? That's a new one on me, from all the engines I
used to rebuild--that Would save a lot of money and time from changing out
the cams to wilder grinds.
