Did you read the December Hot Rod? It was frst seen at SEMA 20009. The "Mopar Underground" at Chrysler loaned Hot Rod a new "street legal" (depending on where you live) Drag Pack (but not fully stripped) Challenger named the "1320 Challenger" with: MOPAR 426 all aluminum stroker "crate motor" rated 556 HP Dynatrac center section with ARB Airlocker differential (still has independent rear) with Dana 60 4.11 Gears Long tube headers with cut-outs Viper 6-speed Viper front seats Interestig Facts here: 1. Mopar now makes a 426 aluminum crate motor. 2. That Dynatrac center section Car still had airbags/ABS/and glass windows. Ran a 12.51/114 first pass. They only got 432/467 on a Dyno. Looks like it needed a little CMR work. ..
