This kit is a jumbled, poor fitting, poorly molded, flash covered disaster. It comes with one basic instruction for one type of motor, but two blocks (stock 351C and 429 Boss maybe?), 3 sets of heads, multiple other belt/pulleys, exhausts, chrome parts that have sprue attachments 1/8+ wide, tearing the chrome completely off. I've given up trying to assemble the drivetrain and will just 3d print one I found. Body is pretty and hood fits nice, but spoilers and fairings don't. Windshield and rear glass are paper thin and don't line up. Dash doesn't fit and is very poorly cast. The absolute worst $40 I've ever spent on a model kit. I can't believe this is an AMT kit...it's that bad.
