Let's face it: The LS platform is a pretty sophisticated thing. A lot of brainy folks in lab coats worked feverishly to make the LS produce excellent power combined with good mpg and clean emissions. Then there is the big-block, whose massive cubic inches and Godzilla-like torque numbers seem go with muscle cars like peas and carrots.
Even though the LS is the new kid on the street and the Rat ruled it with shear size, the granddaddy of them all, the traditional small-block, is still a force to be reckoned with. It's not a hard thing to imagine, considering since the small-block can be built just about anyway you want, stock, budget, gnarly, and so on. We know the small-block pretty much started it all and will be around much longer than these pages you are reading now. We decided to show a little love to our favorite mouse and find the 15 newest products out in the market today. We have everything from dress up items to rotating assemblies and just about everything in between.
1. Billet Specialties new Streamline air cleaners and valve covers offer a fresh new look for your engine compartment. The air cleaners and valve covers are capped off with a 3D machined wing nut and single raised rib complement any exterior trim cues. Available finishes include satin black powdercoat with a polished billet trim strip and also a ready to finish with a polished billet trim strip. The ready to finish is bead blasted and ready for you to paint or powder coat. Stainless hardware is included.
2. The new Comp Cams Ultra-Gold ARC series aluminum rocker arms has design updates and new features that take it to a whole new level. The rockers feature an arced, recessed, contoured design to increase engine power, enhance valvetrain stability and improve oiling, while still fitting under stock valve covers. A new arched channel and contoured top, similar to a bridge design, give the rockers the best strength-to-weight ratio possible. The body has additional CNC contouring to improve clearances for valve covers and springs. Manufactured entirely in the USA, all Ultra-Gold ARC series aluminum rocker arms feature a spring oiler channel through the body for improved lubrication. Trunnion retaining clips have been replaced with an ultra durable spiral lock type clip, similar to what holds a piston pin in place. Stress relieving radii have also been added to areas of the body, trunnion and pushrod seat insert. Even the included locking nuts have been revised to increase surface area to better maintain lash and eliminate wear.
3. Dart's Special High Performance Group has developed pre-engineered, dyno-tested top end combinations that make it easy to build a powerful and durable performance engine at a very affordable price.

The SHP heads are cast and machined in the USA from premium A356-T6 alloy and are available with your choice of 180cc or 200cc intake ports and 64cc or 72cc combustion chambers to provide versatility for different engine combinations. Designed to work with most off-the-shelf pistons and headers, the SHP heads are a true bolt-on package, which offers significant performance gains and legendary Dart quality. These performance-matched top end kits are ideal for completing one of Dart's short-block assemblies or upgrading an existing engine.
