Let the sheet speak:

I was shocked to say the least. At 11.9 PSI it made 737/725, so it picked up nicely with 2 more psi boost. There's more in it too, as my tuner (PBJ in St. Louis) had initially opened the controller too much and it went straight to 15 PSI early and he said it was headed for 800+. He wants to do race gas and lean on it, he's convinced it'll do over 900 on the setup, but I don't want to get greedy with it.
Setup is as follows:
Texas-Speed 377 LS3 Short, stock crank, Eagle H-Beams, Diamond shelf boost pistons.
Cometic 4.010 head gaskets
Patriot Stage 2.5 317's (SCR is 9.25:1, intentionally for off boost non-sluggishness)
Lingenfelter GT2-3 Camshaft
Lonnies Double Pumper fuel pumps
97-98 Rail Conversion
60# Injectors
Stock ported TB
stock 97-99 MAF, screen still in it
LS6 manifold
Powerbond underdrive pulley
160* thermostat
Standard APS TT kit, inlets completely removed and filters directly on the turbo's.
Some thought was put into the building of the motor. I intentionally chose to put it at 9.25:1 to keep the off boost power up and keep it from feeling sluggish. The decision was made to keep it short stroke and large bore because the long stroke APS guys weren't having outstanding results (cubes overpowering the turbo's), and it looks like it paid off. I'm happy as can be, just wish I could drive my car more now. With a new baby in the house I'm the chauffeur to/from daycare since we're using the facilities on base, and my wife will drive the Vette more than me. :thumbsdown: She enjoys it though. :sm_party:
