LS Valve Covers From Billet Specialties Adds A Big-Block-Chevy Look

If you have been wanting to do an LS-swap to your hot rod, but you would really like to keep the look of a classic Chevy, how about an LS that looks like a big block? Thanks to Billet Specialties, you can have just that. The billet-aluminum accessory company has just developed a valve-cover conversion kit that allows the use of big-block Chevy valve covers on the LS engine.

LS Valve covers

Add a traditional big block look to your modern LS.

The conversion plates are an interesting concept, as they are actually the LS’ valve covers. Each side has a threaded oil-fill cap and baffled ¼-inch NPT-threaded breather port. The LS coils mount directly to the top of this billet cover, and have recesses that allow the spark plug wires to exit above each plug for a clean look. The coil harness exits at the rear with ample room for the harness plug. You can finish the big block look by installing your choice of a big block valve covers on top to hide it all.

Now you have no reason to not update to an LS engine, because the LS to big-block Chevy valve cover adapter kits have answered your prayers.
