Power By The Hour main man Jake Long showed how tough he is by lifting the monster Whipple into place all by himself. The Whipple in question is Lethal's Stage 3 4.0-liter kit (PN WK-200243B; $5,642.99), which includes a Super Crusher inlet, a 123mm mass air housing inlet, and Super Monoblade throttle body. This is the same blower that lives atop the 8-second-capable '10 Super Cobra Jet. According to Whipple, this blower is good for 2,518 cfm and 18,000 blower rpm. This blower displaces the same air as a Mustang's V-6 engine, and can create way more boost than a stock engine can handle. So if you want a 4.0-liter, prepare to build a short-block first.
