Charley , that is a very
INTERESTING piece of paper!
I will quote one line from that piece:
"Change Powertrain combination from 'as delivered status' to RPO L-35 - 396 V-8 Engine - M-40 Turbo-Hyrdamatic incorporating 3:07.1 ratio positraction rear axle assembly (Garage)."
Was your car delivered initally with a prior already built engine that was not the L-35 4-speed?
If so, what was the original set-up GM delivered prior to the changes?
I ask this as I still refer back to the 67 VN BB PaceCar I viewed years ago that had a similar changes that resemble this statement released to you on this document...
