lemans skylark cutlass COPO?

[Canuck]

The 68 Olds Cutlass Ram Rod come to mind. Predecessor to the W-31. Came out of Olds Engineering (Dave H jump in here)
Other than wagons Olds only offered their big engines (with 4 bbl)in the 442. In 70 they offered the 455 in an SX. As with most things in the late 60's if you ordered it,was patient,and got the right person than it got built.
To the best of my knowledge though there was no such thing as a w-30 type engine in anything other than a 442 as far as Olds is concerned. Also COPO is a Chevrolet term,not used by any other division. Oldsmobile used a term called Wholsale Car Order Form which was used for fleet (car rental companies) and the Hurst Olds Programs.
