The 360 engine was basically a police intercepter spec engine 225 horsepower at the flywheel. The whole truck for 78-79 was a Mopar Truck Model unlike the Warlock truck option for pin stripping package. Engine option Mopar code for the LRE was EH1 and the VIN has to have a "S" in the Fifth Digit to make it a LRE. The '78 was the fastest American made vehicle in that year. Chev Corvette was the second. Both did about 14 seconds in the quarter............. The whole history is at the Dodge Connection (
