Thanks Doug for the information about the cams.

The info you provided does not appear to be at .050 lift. The reason I say
this because the

duration of both valves at the values you have given does not match the
duration values you

gave at .050 lift.

The duration of IO=37 & IC=61 is 278 and you said duration at .050 lift is
225

The duration of EO=60 &EC=24 is 264 and you said duration at .050 lift is
205.

Any one else has more info about cam timing at .050 lift for 2.5V6.
