DBE's excellent ELN-1 Elan Performance Manual and Catalog lists data for 7
different cam grinds, but not one Cosworth cam. It lists a 576E0111 that
is supposed to be virtually the same as the Brian Hart ZL-1 cam and a
576E0116 that is similar to the Hart ZL-16... but no mention of Cosworth.
The data given in the catalog is in the following chart. Hopefully the
table won't get scrambled during transmission. Adjust the width of your
message window until each cam is on one line. There is a double space
between cams to make it easier to sort out if it gets scrambled.

Sorry I don't have anything specific for the CP L2 Cosworth cam.
Good Luck,
