I figured I'd post my set up and what it has done so far.

Forged LS1 with 4L80E
11.2-1 compression
243/250 @ .050 108/110 cam
Ported stock casting heads
Edelbrock 1 3/4 stepped 1 7/8 98-02 F-body headers
Stock computer / Harness from a 99-02 F-body
3,200 rpm stall
Stock 12 bolt with 3.73's and a posi

Truck made 409 to the wheels in the video but now makes 428 through the mufflers. I started putting the N20 on it last night with a buddy.

Truck weighs 3840 with me in it and has 59% front (2260) / 41% rear (1580) weight bias.

As far as suspension goes, it's got the stock control arms both front and rear. I am running a 350lbs 14.5" spring in the front along with comp engineering 3-way adjustable shocks and 2" drop spindles. Rear has 3-way adjustables as well as classic performance 2" lowering springs.
