LS 408 Silverado ... Exhaust and Burnout
Here is my 408 build. Its a 2003 LQ4 block bored .030 over with a 4"
Callies crank. 6.125" Callies rods and Wiseco flat top pistons. 11.4:1
compression. It has stock LS3 heads, manifold, and injectors. Cam is a Pat
G spec'd 231/239 on a 114+2 LSA. This is a true daily driver and sees the
track maybe once or twice a year. The Exhaust is dual 3" from the collectors to a
magnaflow muffler. Single 4" out over the rear end. The truck Dyno'd 434hp and 400ft tq
through a built 4L80e. This is my first LS motor so I didn't know anything
about the tuning process. I had a speed shop tune the thing when I first
got it started. Then it went directly to the Dyno. After my research and the
purchase of HP Tuners, I think it has at least 30hp left in her. But not
bad numbers for stock components through a 4l80e.
