Sometimes it's hard to tell overlap without the actual IVO and EVC event numbers and what lobe profile is in use. See if the original owner has the cam card or find out who made the cam and get one.
That is a lot of cam for a 5.3 so i'm guessing the engine you're looking at is much bigger? If you're going supercharged you don't really need that much duration especially on a 6.0 or smaller engine.
By all means though, since it's not in the 230+ intake range on a short (like 108) center you should be "OK" to boost it. Boosted engines actually like a couple of degrees of overlap since it takes advantage of charge momentum through cylinder scavenging.

Too big.
