Finished an 02' Z-28 Dyno = 430RWHP w/Emissions Friendly Cam & Heads Hey guys. Just wanted to throw this up on LS1Tech as well.
A.I.R. completed a project car last month, after break in of the new Clutch and 4.10 gears which took a few weeks, we finished Dynoing the car this morning. I'm very happy with the results of Todd's 02' Z-28. Todd wanted MAX Power and still pass emissions, it's a juggling act to get best performance and still pass the sniffer, so after doing some math on a new (smaller) Custom Grind Cam, and getting him the right combo, the car put down some impressive #'s. With stock 3.42 gearing she would have put down another 5 to 10RWHP. The Cam pulls Torque very well through out the entire rpm band, and lowering the idle to 725 rpms will still provide some pretty good lope from the exhaust.
Engine Specs = Stock LS1 346ci (non LS6 block).
Original Fast 90mm Intake and 90mm TB, unported
Lid w/stock paper filter
PRC 5.3L heads
A.I.R. New Custom Grind Cam (emissions friendly), nick named "E-Max Cam" 224/228 Duration on a 115 +2 LSA
Pace Setter 1 3/4" Headers w/off road y-pipe installed currently,
Spec Stage 4 Clutch
10 Bolt w/4.10 Gears
Dyno pulls were done on 91 Oct gas, 30 deg of timing and A/F 12.5 to 1 at WOT which netted best numbers and still safe, the car put down 430RWHP and 381 RWTQ, thats just over 500 Engine HP from a N.A. Head/Cam LS1, not too bad.

we have 430rw cars out here that pass the visual and sniffer in ca. We can get the sniffer to pass on as big as a 226 single pattern 114lsa with a nice set of heads... its been done.
