reproducing build sheets is illegal, chrysler has a copyright or trademark of some kind on them. call galen govier of gts for a breakdown and letter of registry for a fee. i had a yellow 71 rr in 72 with the black canopy vinyl roof, in virginia. 383 auto. its the heads, crank, and cam from a 440 that makes it a hp motor, 71's were rated at 300 hp but that was after the the change in how hp was calculated in order to help with the crazy insurance costs. i'm restoring one now, if you need more info, email is rodee71@gmail.com. good luck, Bob
