Keep in mind that Dyno2000 loves to give a lot of low-end torque, and assuming 700cfm, TPI, 355ci, Small-tube headers w/mufflers, and your cam with 108 intake centerline (by the way, which cam is this?), your readout is as follows:

RPM HP TQ
2000 147 387
2500 187 392
3000 226 396
3500 269 404
4000 307 403
4500 329 384
5000 337 354
5500 324 309
6000 293 256
6500 251 203

The flow numbers I used were:
.1 68/55
.2 128/104
.3 179/140
.4 205/156
.5 221/166
.6 225/170

From what I gather, these are CLOSE to the real world, but yet, when you through in variables like timing, port/polish intake, etc... who knows?

I've made both my engine thru Desktop Dyno 2000 and in the real world. The HP numbers DD gives were within 5-10 HP of the real world, while both times the torque numbers it shows were way lower than what I dynoed. It seems DD doesnt give enough torque to the TPI setup, because I can switch the intake from TPI to carb and the numbers barely change.
