They haven't even been released and it's started... TTOTD
But, I am pretty sure it will easily be more powerful than the Roadrunner, and I don't think Ford is concerned about hurting the Boss's reputation and Heritage by rating it higher than the Roadrunner.
Also, the rods are sinter forged, instead of powder forged like the 11-14 Coyote, nor do the composition of the rods determine BHP.
It will most likely be rated 7,500RPM from the factory. Larger intake and exhuast valves will make for more BHP, revised heads again, more BHP, and the CMDP will allow more torque in the low to mid range but will "hurt" top end by 5-10BHP. They've also changed something about the TiVCT, but in the end, it's all assumptions until Ford releases final BHP ratings and Tuners get their hands on them and work their magic.
