You need to supply a photo of many things here to get those questions answered.
Like the Vin Tag-Fender Tag-Motor & Trans Pads.
Seems like you don't have time on your side if your dead line is tomorrow morning at 10 AM.

Scat pack cars are part of the Performance Dodge Line up of all the R/T cars and a Dart Swinger that would all get the Scat Pack sticker on the quarter glass windows. all the scat pack cars for 1971 had a minimum of 340 cubic inches with 4 barrel carb all the way to a 426 Hemi.

If the car is in fact a Challenger R/T there should be a JS on the Vin Tag and Fender tag for starters.
