I am looking for torque information, specifically the torque curve diagrammes, on the following engine options as installed by the factory in the 1970 Cutlass Supreme and SX:
L65 350 LC 2B Carb
L74 350 HC 4B Carb
L33 455 HC 2B Carb
L31 455 HC 4B Carb
W32 455 HC 4B Carb

Can anyone point me to this information?
Thanks, Peter

I have a photocopy of two pages of torque/horsepower curves of most of the 1970 Olds engines (I'm assuming the mid-year introductions were not included). Unfortunately, the copy quality is so low as to be virtually unreadable on my copies; attempting to scan and post them would be worthless.

However, I believe these pages were from the 1970 Dealer Album -- yes the really expensive 2-volume set. Pages 78 and 79. Maybe someone with an album will be willing to share.

Of course, the next problem is whether or not to believe the charts. Even if they are based on Engineering data, how much did Marketing -- or Management -- modify them before publication?
