I had both sets of cams with a schrick vgi in my
corrado vr6.  Dyno results showed more power and
torque with the 256's until 6000 rpm, then the 268's
would pull away.
Street driving the 256's felt pretty good, but the
lack of top end vs the 268s was very noticable.  After
6000 rpm or so, the 256's are done whereas the 268s
will pull to 7000 with no real problems.

Depends on where most of your driving is in the rev
range and how much you want to spend...

Nope, I don't have any scans of the dyno sheets.  I'm
still using a 56k modem!  :-)

Not a huge difference, but definately enough to feel,
looked to be around 6-8hp all throughout the band till
6000 rpm...

Just dyno'd some TT 288s the other night in a 3.1, VGI Corrado with a Collin
head. We went from 268s to the 288s and picked up 13+whp from 5500-7000! Not
the best idling cam I've tested though :)
Best regards,
