True that. Would not be surprised if he added ballast to certain sections of the rear. I believe those pups already have aluminum hoods. I suspect most of the weight is in the doors, interior and dash bulkhead section. It would be a challenge to narrow down the weight of a street Challenger.
A friend has a new style Challenger drag car. Full dash, door panels, interior trim, power windows, 6.1 N/A, 904, 8 3/4, all stock body. Less than 3100 w/o driver. Looks bone stock except for the seats. Doug
