Sweet, this is about the combo I keep thinking about dropping in my heap.

My guess is you'll beat that 550 RWHP.

Let us know how it turns out.

At first, I was thinking- "Dream on, I mean LS engines are good, but 550rwhp from a 6.0. Let's be realistic." And then I saw the hair dryer...

Good luck, let us know.

What fuel are you running? Do you plan on water/alky injection? How much timing is in your tune? 14 psi on 10:1 compression with 91 octane should be interesting long term.............

The LQ4 is the perfect stock block to turbo with 9.4 compression, not 10:1. Im doing a LQ4 with L92 heads and LS3 intake, and a 76mm turbo. Good luck on the dyno, interested in the results

Looks Good. Let us know how it goes. Little concerned with the upper rad hose though. What hood are you running for clearance?

read it as an LQ9 which is just over 10:1..............

You're the 2nd guy with a 2nd gen I've seen get that Vortec truck intake to fit.

What did you your hood to get that truck intake to fit ??
What engine mounts and frame mounts did you use???

Looks cool, good luck!!!

Top pic= little hood springs=fiberglass cowl hood. That's my guess.

What were the numbers?

I have all that minus the turbo, I did get a custom cam ground though so who knows. I'd like to see how yours does with the LS3 top end on it.
