yeah not to mention my numbers were on an 07 6.0 LS2, the new 6.2 LS3 not only are a bit bigger but have the better flowing Z06 style heads and intake manifold. The same mods as i have usually net in the 460-470whp range. On pump gas!!

 

Bolt-on mods and engine builds are for the birds. If you want to make real power, you need to invest in stickers. Our cars have plenty of room and each one is good for +5 whp. Fact.
