LSx Valiant Build. Take a look inside...

Can say one thing about the LS platform, it can take some boost. Think it was the Dec 11 Hot Rod that took apart a 4.8, honed it (one hole had a rust stain after honing), loosened up the factory top ring (no new rings) changed the cam and did a bit of head work. 25 pounds of boost and tried to kill it. Over 1200 hp before the factory ignition crapped out.....think it had 70 or so dyno pulls on it at this power level.....
