The mean spirited 427ci V8 L72 is correct, original and numbers matching. It sports the correct MN stamping code, correct Holly Carb, 3959164GE List 4346 983 is atop the correct intake manifold direct from Chevrolet. A numbers matching 4-speed manual Muncie M21 transmission is strapped to the rear of the menacing mill, and a correct posi trac Eaton 12-bolt 4.10 rear axle is noted. One must understand how rare it is for a Yenko Camaro to retain its original drivetrain. Most were thrashed, abused, crashed, or ridden hard and put away wet so this American Icon is truly a shining star.
