From the article:
Engine performance comes from a heavily built, RSI-assembled 2.5 stroker B230F running a billet crank, H-beam rods, turbo tune pistons, prototype Stage 2 cylinder head, Stage 3 cam prototype, a Holset/Garrett hybrid turbo and more detailed in the ad. Output varies from 325 to 427 HP at the wheels depending on which tune you use, and the motor certainly sounds built to withstand high boost.
