Edmunds got 388 RWHP out of the CTS-V stock, so it seems the 420 crank HP is actually underrated a bit. We'll need to see some more dyno pulls on stock ones to see if this was an outlier. Edmunds also got 415 RWHP out of an LT1 in a Z51 Stingray which is supposed to be 460 crank HP. So it may mean Edmunds has a happy dyno.
