Not in a Dell. Dells are designed to just barely get by with their cooling (for silence). You'd definately need to upgrade the cooling for stability/not throttling. 3.73 is possible with good air cooling though. Not sure about stock vcore. So far the only overclocks I've seen with stock vcore are simple Suicide screens or else running on cascades. I'd say 3.6ghz with upgraded air cooling on stock vcore wouldn't be too hard, but that's mostly a guess. 3.73 I'd suspect would require a little extra vcore.
