Distributor Over-Advancing

This cam won't be kept for too long, I've been using it like this for about the last 3ish years, and 60,000km, so I recently got new springs and retainers and have a new camshaft on order, I'm expecting to install it on my holidays last week of may, this is the cam I ordered:

Voodoo Hydraulic Roller Cam - Chrysler 273-360 (W/ Short Snout) 264/270 - Lunati Power
