Dynoed the car last week. It was extremely hot, and humid, but seemed to put down good numbers.
6.0/LQ9
EPS (Pat G) 226/234 .598”/.602” 113LSA +4 advance
LS3 Heads/Intake
92mm TB
1-3/4 headers, with dual 3"
4.10's
SD Tuned
Made 457/433
I figured I might make more power with 1-7/8 headers, removing maf (I'm SD tuned), and a cooler day. I'm happy with the numbers since I was only hoping for 450.

Love the torque. Any time you make over your cubic inch displacement in torque by 3000 rpm, it's a nice combo. Glad you're pleased. Tell Brian nice job tuning it too.

Yes, Brian did a great job tuning. I'll probably go back when I get 1-7/8 headers, and see if it will help any.

The LS3 stuff always impresses me. I've been kicking around a junkyard LQ/92 build around in my head for awhile now. I'd imagine similar results with a proper cam? Is PTV clearance an issue at all or is this a bolt on and go set up?

Lovely torque
That SHOULD be measured.

[QUOTE=WKMCD;15270282]I've read over and over on the Interweb that the L92/LS3 heads are weak on the bottom end. Something about the intake runners being too big... ![Rolleyes](https://ls1tech.com/forums/images/smilies/LS1Tech/rolleyes.gif)
Nice work and congrats on not over-camming![/QUOTE
Well The Size of the port VS the Air they Flow I consider them Weak in stock Form, They Make Good power because they have good low-mid lift flow imo, ported thats another deal
457-430 is Awesome Power Good job!

Did you mill the block at all before installing the heads I have a ls2 I'm about to stroke. Would I have to go with bigger valves if it's stroked? I know I'll need stroked springs and roller rockers for the cam. That should hold right?
