Chimera Billet LSX

MAIN-2 

Filling the hole in the marketplace for a no-compromise, all-out LS head is our Billet Chimera LSX. Just like the mythical beast, our Chimera is a combination of several very powerful and efficient cylinder head designs rolled into one with a little of the Frankenstein magic thrown in for good measure. Featuring radically rotated valve locations, canted valves, extremely tall raised runner intakes, and high flow exhaust ports that turn the air inside the port to avoid crashing into the headers, we have created a monster that is unlike anything else in existence.

With this head we wanted to show the racing world how to truly think outside the box and to demonstrate our capabilities as a custom cylinder head shop. Most designers allow themselves to be limited by parameters that will make their heads work in a large variety of applications, while we focused on simply creating the best LS heads on the planet for the top echelon of competitive racers.
