Advancing B303 cam

[plum819]

Hey I know alot of people think its junk, but ive got a B303 CAM Im installing on a stock block with cast iron gt40s and an explorer intake.I talked to Mike at Thumper and he suggested I advance it 4 degrees. Im also putting the Crane 1.7 RR's as well. I didnt mention that to him. Just wondering if that changes anything. Anybody have a similar set up?Would you advance with this setup?
