For a street car, buy NOTHING based only on "peak" power.   Any car needs higher average power to be quicker, and a street car especially needs a broad torque curve.  Read all about Jim Hand's wagon to prove that.

Those TF GenX 255's make good power everywhere! :yes:

Running the CNC-ported heads on the otherwise stock LS3 resulted in a jump in peak power from 493 hp to 505 hp.
