I am sorry, but I am still standing by my original opinion that someone added decals and badges to your car - nice car that it is. That "Rocket 455 L31" thing on the trunk lid should say "Delta Custom" I think someone either ground the lettering off of it, chromed it, and engraved it - or just went out and got chromed bars close to the same size and did the engraving on them. Same for the fender emblems - there shouldn't even be anything under the "Delta 88" on the fenders, but those bars look to be the same size as on the trunk, so somebody just made three of them up.
Now, as for your engine figures. I see now what you are looking at, and it is all for 1970 models. The W33 was not offered after 1970. NOTHING in '71 had a 10.25 or 10.50 compression ratio. The maximum compression in '71 was 8.5, hence the lowered horsepower ratings. Yes, the L31 had 365hp and 10.25 compression in 1970. But for '71 it was only 320 and 8.5.
The figures presented on that web page are for 1970, though it doesn't specifically state that.
