Lost my cam card, Indy CM3 - 03/21/11 11:45 AM

As the title of the post suggests, I've misplaced, thrown out or lost the info. Cam is an Indy CM3, I can remember most stuff but not the recommended lash settings Anyone using the same cam who can share the info?
I can only blame old age
TIA

Don't know about that cam Tig maybe call Indy?...........or break out dial indicator & measure lash ramp , multiplying this figure by rocker ratio will net lash settings.

Now that you found it,
can you post a scan so people can save it and help the next guy?

Sure, but since I don't have a scanner I'll type it.

Valve overlap 65.8 crank deg.

Intake
Valve opens 32.3 'BTDC
C/L 108.5 'ATDC
Duration 282 Crank deg
Valve closes 69.7 'ABDC
lobe lift .479 in
Valve lift (1.5) .719 in

Exhaust

C/L 116.5 'BTDC
Valve closes 33.5 'ATDC
