I have the older two carb motor.. just wanted to see the tq curve.. havent found anything in the google machine

Merc is pretty secretive about that stuff. I doubt you will find one unless somebody has dyno'd a fresh stock rebuild. Cahnces are most people would do some HP mods on a rebuild.
I would expect a very flat torque curve that starts falling off around 5000rpms and makes peak HP around 5200rpms.

BTW, yours would be the 600SC. The 600SCi is the newer EFI version.

I noticed its a secret.. not sure what the secret in a dyno sheet is about but ok
