Build is Finished!

Congrats on finishing it!

I see you went with the Bilstein shocks. Which ones did you get and what's your assessment of them coupled with the Belltech coils?

After two unsatisfying tries with Belltech SP and Monroes shock/struts I went with Bilstein 4600s. They aren't as stiff as the Belltech SP shocks I first installed; which are great for eliminating body roll if you don't mind being jarred going over bad roads. The Bilsteins produce much less body roll than the Monroes. Ride quality is good, but not as smooth as auto airride. If I had it to do over, based on what I've since learned, I'd keep air ride suspension and use longer extension rods to lower the rear.

absolutely gorgeous! I aspire to get my Denali restored to this caliber.

Thank you. Its been a labor of love!

Putting the ls364 in my 02 Escalade ext, will it run so I can drive it to the tuner?

It should. My engine installer drove mine about 15 miles to get it to the tuner. He said the fuel tables were off so he drove "gingerly" with slow acceleration and never going over 50mph.

That is sweet... I built up an LQ9 and 4L60E in my setup. Pulls hard but doesn't really accelerate like I thought it would. Will go up about any road though with ease... curious how yours pulls. Have you dyno tested?

The engine is spec'd by GM Performance at 452hp and 441 lbf-ft torque. These are flywheel specs. Below are dyno graphs which compare this engine to a stock LQ9 and another of rear wheel numbers from the dyno run of my engine. Based on these numbers, the tuner used a formula for drivetrain loss and enviornmental compesantion to estimate factored flywheel numbers for my engine at 455hp and 447 lbf-ft torque.

You might consider swapping out your stock LQ9 intake manifold, fuel rails, injectors for the TBSS setup with its larger throttle body. This should add a little pep.

Still tweaking the little things. Here is a photo of the air intake cover I made.

Looks good. Fiberglass?

Man that is awesome!!! I want to do a rebuild on my Tahoe. Just body work and paint for now.

Here is a dyno comparing stock LQ9 with the LS364/450. HP and torque is improved across the curve.
