1.7 rocker guys, how did it affect torque?

[pjtoledo]

for those that did the 1.7 rocker upgrade, how does it affect torque at and below 3000 rpms?

this will be a 95% daily driver and I'm concerned the increased lift will reduce power where the engine spends most of its time.

has anybody done just the intakes? I'm thinking doing only the intakes will keep the overlap down. yes, I realize the timing events will be the same, but the slightly increased lift at the ends of the ramps will effectively increase the scavenging and overlap.

remember the cam lobe opens & closes the valves, no change to cam profile then the valves still open & close at the same location on the lobe ramps regardless of what rocker ratio you use.
