2003 EB Z06
Stock Baseline 353/347
Stock Dynotuned 360/357
Blackwing w/tuning 371/366
Stainless Works headers w/cat delete 387/373
Same as above with Air/Fuel tweeked 393/385

We have since added our RGR stage 2 heads ($1799.99) and SLP 1.85 rockers ($429.99), GM head bolts ($60), and Cometic head gaskets (72.99 each). The new numbers are
424RWHP/393RWTQ. We still need to tweak the tune a bit, so maybe there is a few more in it.

I have very pleased considering I have retained the stock idle quality while making good power. It is slightly louder because of the offroads (which I like). With the better valvetrain components, it does have a bit of the typical LS1 "sewing machine" sound, but I can live with that.

I am very curious to see what kind of power we would make with a "thumper" cam, pulley, aluminum flywheel etc. Although I think 450-460RWHP is realistic, I am going to stay with the "sleeper" setup for now and probably add nitrous.

a pulley and one of these fancy EWPs would keep it driving like stock should kick you up over 430-435 rwhp. I like the sound of that setup

With the stock 1.7 rockers, the cam is 204/218 0.551/0.541 117.5LSA

with the 1.85s it becomes:

206-208/220-222 .600/.588

I'd be interested in what the heads alone were worth, and what the rockers added if any..
