At stage 2 the risk of bending a rod is very possible. Typically around the 650-700 whp is pushing the limits of the connecting rods. To prevent bending a rod you will need to build the motor to handle the additional power and stresses increased by that.

Thanks for the response guys. I will be sure to keep you guys in mind for the rebuild if I ever go down that route. I’m thinking of going bm3 stage 2 off the shelf tune if that makes a difference. I see that their tune is more conservative than your stage 2 tune. Do you think that it would be fine at those levels? I think their website states around 660 rwhp and 660 rwtq.
