They did not build a W31 in 1971, 1970 was the last year. The 260hp listed was the top 350 available that year, available across the Cutlass lineup.

 

This is right from my '71 442's original owner's manual:
Non W-30 455 4-bbl was 320 hp @ 4400 rpm (250 hp net @ 4200 rpm)
W-30 455 4-bbl was 340 hp @ 4600 rpm (270 hp net @ 4400 rpm)
No torque ratings are listed but I have seen published figures of 460 lb/ft in the 1971 spec sheets I recieved from GM.

 

These "facts" remind me of the old joke where one guy steps on one of those "get your weight and fortune" scales. He reads the slip to his buddy. "It says I'm smart, handsome, and will be coming into a sum of money."

His buddy looks at the slip and says "Yeah, and your weight's wrong too... "

Badda BING!
