Default 07' Classic Silverado rebuild, 408 and FI billet S484/96

Some of you may have seen her before but its going through a rebuild again, pulled the forged 370 last October after the last Colorado Street Outlaws event. Lifted the head(s) a tad I think, was building pressure in cooling system after a hard pull but fine if driven normal otherwise. She had been good up to that point and has gone 10.8 at 127 on 20" street tires/wheels with a 9000ft+ corrected DA and a 1.6 60'.... also weigh's a healthy 5,050 lbs with me in it. Plan was to replace gaskets and studs and go back together but ended up selling it all and upgrading New setup is a ATK forged 408 short block with PRC 260cc LS3 heads and a JFR spec'd cam, also ditched the old cobbled together Garrett 80/83 turbo in favor of a Forced Inductions Billet S484/96. Here are a couple before pics and video...

See....this is almost exactly what I want. Only on a leveled 2500 since it will already have the 4L80 or 6L90. And maybe an extended cab.....but must be 4x4!

Sounds good, 4l80e swap isn't too bad really, 4x4 makes it fun, my t-case is manual so you can do some nice burn outs in 2wd and then lock it in and pull 1.6 60's on street tires.

It was a base model W/T truck when I bought it, rubber floor mat and AM/FM radio lol, wife couldn't believe it didn't even have a tape player.... she hated it then.... I like the manual t-case as well, less to go wrong!
