Another "what will it make", but a little different

I've taken 7 cc's out of LA open chambers before, but careful where u grind it from, start off by sticking the heads on the bored block and from underneathe/crank side of the bore scribe the overhanging deck of the heads 'the chambers are always smaller in circumference than the bores themselves' . Starting that way and remeasuring will hold off on changing the chamber design/overall shape which will effect flame travel , possibly in a negative way.

When does the intake valve close with that cam?
I think the cam will be a really nice in a street car with that @.050 duration.
