but it is a GM A body. I have owned it since 1986 when my dad brought it up from Phoenix. It's a '72 with most of it's original factory applied paint still showing. Engine is a mild Edelbrock headed 461 that makes 498hp and 536tq on 87 octane. Compression ratio is only 9.3-1. Trans is a TH400 with a manual valve body and a 10'' Continental converter. Rear is a complete Moser 12 bolt with 33 spline axles and 4:10 gears. My best e.t. to date is 11.34. M.P.H. was 116.97. Best 60' is 1.55.
