You didn't give all your cam specs. What's the duration @ .050",
Lobe separation and where is it installed?

Unless you have fuel delivery problems or really low float settings,
my guess is, a combination of cylinder head and small exhaust
is currently keeping you from running 10s.

11.17 is pretty quick for 117.55 MPH especially, since you have
mediocre 60 fts.

There is something definitely choking off the power on the top.
