Looking for info on my 68 charger R/T

Looking for any info, original motor/trans, fender tag, build sheet, anything I can find on my 1968 charger R/T. Original 440hp car. The car was a drag car down in florida for most of its life; car name was "the hulk", and the "pot o gold" later on. If you have any info, please give me a shout.
