I do run the 727, but have a manual valve body. When I was putting it together, there was a debate on this and I believe Dwayne said it was OK.
there was also a debate on the transmissions and at the time, it was worked out that if you ran a 904 (or any non original trans in other brands) you had to use the current HP rating, but if you ran the original (727, etc) you would get a 10 hp reduction for carbs (5 for FI cars).
Like I said earlier, I haven't raced for awhile so I don't know if anyone still uses this, but it was never made official and I still use the rated hp because of that. So I am at a disadvantage due to that....plus my valves are stock with no back cut...probably why I only run .1 to .2 under, among other things...
