Didn't single you out, the survey was for "cobra replica owners with motors built to perform". Your public profile says you're "cobra-less", can't help if you decided to jump into the fray
Survey so far is pretty clear on what most would like to see in a dyno run, google 427 CID dyno charts and look at what images come up.
The only way to know if you have that nice broad and flat torque curve is to measure it, and 2500 RPM should not be where "you're pulling the guts out of it" - I just don't buy that period.
