350 Cam Intake Valve Closes

Need the degrees after bottom dead center that the intake valve closes for GM
14060651 camshaft. This is the cam used in chevrolet trucks with 350 engine from 1984 to 1996, along with certain current GM 350 crate engines.
Thinking some where around 62 degrees.

Thanks

Aussie, Thanks for the information.
Looks like the dynamic compression ratio is kind of low, with the intake valve closing 90 degrees after bottom dead center.
