Dwight's site is not incorrect.
It's the operator that's incorrect. LOL

Just look up the body style, one at a time..You are confusing yourself the way you are doing it.

OK, thanks for the info. I've never seen that page. Don't know yet how to call it up. But I don't understand why the non-birds are shown with calculations using the 260hp factor on this page that you linked, and the 283 factor on the page I was looking at ? It just appears to me that it is not possible for both pages to be correct. Seems it has to be one way or the other ? But then, what do I know ?
