As a help, measure the height from underside to tip of the lobe( top)

 

Then measure the narrowest width across the middle of the ground lobe, ( called base circle diameter)

Subtract one from the other, this will give approx lift at cam.

Multiply by 1.5 ( approx rocker ratio) to give a valve lift measurement.

 

If it is ex L26 it should be centre bore drilled, ie internal oiling, if not, these can be drilled.

 

As far as duration and timing, it needs to go into a dummy assembled head/block.

 

Generally a reground can be anything from a 68 deg to a 72deg.

 

Yes it should be fine with 3x 40's, as the 40's wont suffer from slow airflow at idle.

this is the info that was given to me from person I got it off:-

In regards to the Cam here are the specs from wades site-

 

 

Profile  Lobe Timing      Duration      Valve      Valve  Lobe    Rocker

No     Lift        Ad          @ .050          Clr          Lift      Sep      Ratio

                        Open                                                                  1.55

                        Close

733a    Ex      65-25        220.            012        .484    110

            .320    25-65        220            .012        .484

            In

            .320

 

Smooth idle, good torque

2000 - 5500

Its a very streetable cam profile.
