NEW: C5 LGM Longtube Header Install
The headers are a full 32” True Long Tube header that has been dubbed, "The most powerful C5 header on the Planet”! This header includes a complete header with a 3/8” flange and incorporates a “Race Style Merge Collector”, to a full 3” X pipe, and continues in 3” right up to the original 2 bolt muffler flanges. This makes this a full bolt on application that requires NO cutting or welding, and leaves the factory system completely intact incase you ever want to easily put the car back to stock. (C5) More...

Did you know?
LS6 blocks (which, starting in 2003, are also LS1 blocks) are made of a slightly darker duller metal than the pre-2003 LS1 blocks. This may be an easy way to tell what kind of block your car has.
 
LS1 to LS6 PCV conversion
So many LS1's have oil consumption issues and GM took a stab at fixing it on the LS6. In this article I show you how to convert your LS1 over to the newer LS6 style PCV system. This will require cutting away a small part of your engine block, however, it sounds a lot scarier than it actually is. This mod can be done for about $65 in parts. (F-Body & C5) More...

Infopic: Y-Body vs F-body underdrive pulley
Both of these pulleys are ASP underdrive units. As you can see, the LS1 crank pulley on the vettes looks quite a bit different than on the f-bodies.
