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.

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.

4. The Ultra Street Avenger carburetors feature an all aluminum construction and are equipped with metering blocks and base plate made from 6061–T6 billet aluminum. Three different anodized color options (Red, Blue, or Black) allow for a personalized look while maintaining the ultra–high strength and durability you get from billet.

These carbs have the same great features you expect in a Holley: tumble polished aluminum finish, quick change vacuum secondaries, four vacuum ports, factory preset "no trouble" electric choke, built–in fuel filters, and an included fuel line. In addition, the Ultra Street Avenger now comes with anodized metering blocks and a base plate made from 6061–T6 billet aluminum and a built in, clear fuel level sight glass for easy, no mess fuel level adjustments.

8. Performance Distributors new Slip Collar D.U.I. distributor features a slip collar with 7/8 of an inch in adjustability.

Performance Distributors calibrates the advance curve on a distributor machine, which optimizes the advance curve providing instant throttle response and performance throughout your rpm range. The distributor comes complete, including the Street/Strip D.U.I. Coil (or Racing Coil) and Dyna-Module, which allows you to open up your plug gaps to 0.050- to 0.055-inch, burning your fuel more completely. Of course, this unit also incorporates the company's brass terminal cap and rotor, available in red, blue, black, yellow, or clear.

12. These Pro Elite 23-degree CNC-ported aluminum cylinder heads are from RHS. Engineers at RHS have recently designed a 23-degree aluminum head that is CNC- ported from the factory. The precision accuracy and durability are derived from the precision CNC-porting of the intake and exhaust runners, as well as the combustion chamber. The heads feature CNC-ported 228cc intake and 82cc exhaust runners. The 2.055-inch multi-angle intake and 1.600-inch radius exhaust seats allow for superior airflow, CNC-ported 69cc combustion chamber relieves valve shrouding & improves airflow efficiency

14. Small-block Chevy engines are capable of making big horsepower. However, durability at high rpm can be compromised by an inferior flexplate. In order to prevent this common failure in performance applications, TCI developed a precision stamped steel flexplate that is 0.035 of an inch thicker than factory flexplates. The extra thickness will provide years of reliable service, making it a must have for any internally balanced Gen 1 performance application. The ring gear is custom machined to form a perfect I.D. circle before the flexplate is welded in place on both sides. This creates a better, stronger fit that minimizes runout, ring gear bounce and other damaging problems. The 168-tooth flexplate is dynamically balanced to eliminate potentially damaging vibrations and electro-coated to protect against damaging elements.

15. Leave it to Trick Flow Specialties to make a better carb intake manifold for the small block Chevy. The CNC-machined aluminum manifold has integral bosses for nitrous nozzles and extra material for custom port work. The dual plane design has high-flow individual runners for increased torque; air space below the plenum works to keep the air/fuel mixture cooler for additional power. It's designed for 4150-style carburetors with a basic operating rpm range of 1,500-6,000 rpm.
