Anyone have any tips for cam tuning on stock cams in an 8?

 

Are you looking for better topend pull? If so, you might try -5/-5. My buddy, JRSimon, uses this setting for drag racing with the stock cams in his VIII motor.

 

any idea of hp gain?

 

HP for the -5/-5 setting in comparison to 0/0? Sorry, I really don't know! You can P.M. JRSimon(EvoM username). JR can give you all the info concerning both, -3/-3, and, -5/-5, with stock cams on a stock 16G.
