Thanks for posting your results!
Few thoughts:
Tq seems low to me (I don't see in your post ig you're 29.2/V81, but even if you are, I would expect to see tq a good chunk above hp). Also, why run 100 octane? Do you run it everyday, all the time?
Last, did you get in a full, clean 1/4 mile run for your dynolicious to read the 346 whp? I rarely have the room to run like that, so I often have to settle for shorter blasts to get my readings. That said, I haven't come that close to 346 whp (using 0% loss, and 3500 lbs), on my brother's car with the JB3. I think it was something like 306 and 330 the last two times I did it. Granted, that's with 1.0, not 1.1, and that's some statistically scarry variation in numbers to accept them as being accurate.
FYI - The only full 1/4 mile I have been able to fit in was on a SLIGHT (maybe 3-5 degrees) uphill, and I recorded a 13.1 @ 111 mph, so figure if it were level and I launched harder, it'd be a 12.7 @ 113 or so, which I guess if near par for the JB3.
