Reconfirmed TDC and very repeatable.
The info I found on the 77B: Int and Exh durations 260* or 220* at .050"
Lobe separation 111*, lift .325* Lash .014".
I got: .050" open at 148*
Exhaust starts to open @ 120.5*
Exhaust starts to close @ 348.5*
Exhaust is closed at 9* ATDC
Exhaust Lash is .014"
Is this enough to get a feel for the cam location? What else need I do. Exhaust centerline?

Russ, In your numbers you say the exhaust closes at 9* ATDC, the 77B is supposed to close at 19* ATDC. That's 10* early, If you closed up the lash what would it close at?
