Another Stock Bottom end LT1 breaks 400RWHP!!
Thanks everybody!
I`m getting ready to go to work so i`ll answer most ofthe questions and try and post the graph this weekend.
These are SAE corrected. I made 3 pulls first was 391.9, 2nd 403.7, and third 395.6. 2 weeks ago I only dynoed 366 but got a reflash and changed the exhaust around a little.
Because of the stall and possibility of downshift the dynoshop did not want to hit it very early, my grapgh starts at 4300rpm past my peak torque. So i don`t really know my peak torque numbers.
max horse power was at 6150rpm.
here`s a sample of the graph as best as I can tell, 4500rpm=275hp,340tq, 5000rpm325hp, 346tq, 5500rpm=355hp, 348tq, 6000= 380hp, 346tq, 6150rpm 403hp, 345tq
I wish I could have seen peak torque but it was flat.

here`s some answers to your questions:
max power was at 6150rpm the a\f started to get a little fat above this.
cam is XE230/236 112 lobe sep lift w\ 1.6 rockers is .544in/.555exh
52mm AS&M TB
SLP 94-95 style headers off road pipe, magnaflow catback
Ed wright tuning, same as Ken95z28.
Next year I am getting LT1 edit for OBD2 and going to Carolina automasters for a dynotune. Mainly to smooth out the idle its rich, and clean it up a little over 6k. I`ll also be getting a different pcm. After my build this year i ran out of money and since i already had Ed wright tuning for my bolt-on car, it only cost me 150 for the reflash, and the second one after the wideband was free.
I will try and get the dynograph posted soon.
