In a word, YES! The 440 moves the Charger well, it’ll do a better job moving the Scamp and do it easier.
Look on the Scamps and Chargers reggie to find the weight of the two cars. For every 200 lbs, consider it like you threw a friend out of the car and the performance will pick up a little bit each time.
So, if there’s a thousand pound difference, that’s like loosing 5-7 average-ish people from inside your car. At this weight reduction level, it will equal approximately 1/10 quicker in the 1/4 for every 100 lbs. Or something along the lines of 50hp per person that leaves the car.
These are loose terms but accurate enough for the generalized discussion we have on hand here.
