Since this car competes in NHRA’s Stock division Donato had to utilize a rear-end. assembly manufactured by Chrysler under the Drag Pak car. He opted for the rear-end assembly made for the company’s  Jeep Grand Cherokee.  It was approved for use by the NHRA. The shocks and springs Donato uses on all four corners  are manufactured by the AFCO folks. The rear gear ratio they are using right now is 4.56 which is coupled to a 904 Chrysler three-speed Automatic with a 2.74 low gear.

For Indy Donato is changing the converter and the headers. “Our headers we tested at Cordova had too big of tubing. We are going to install headers made of 1-7/8 tube and a converter that will allow us to shift the motor at 5000/5300 rpm,” he told us.

John Donato estimates the engine in Garlits’ Challenger makes 610/620 hp and 460 ft-lbs of torque. It has a single Holley 1000 cfm throttle body. The engine mounts for the Drag Pak cars are placed so that the engine is located 19mm right and 75mm back of stock location.
