The LS3 525 beats the stock LS7 across the board. Better HP and Torque

My 69 with the LS3/525 pulls my Corvette ZO6

Change the cam in the LS7 and 620-650 hp and 550 torque are easy #s to achieve and still very street friendly.

My last 69 I used an LS7 with a Texas Speed cam and ran 505 rear wheel at only 6200. Car was a beast. However my LS3/525 is also killer setup.

I just bought another LS7 for my kids build. Of course will do a cam change and convert to wet sump. Funny part is that just yesterday we started talking about selling the LS7 and buying a LS3/525. The money saved would pay for a lot of other stuff.
