Budget Performance Heads
Thanks to a new combustion chamber, EQ's new small-block Chevy cast-iron heads are designed to accept either a flat-top or domed piston, allowing oval track, street, and drag race engine builders even greater options in their quest for speed. Developed for maximum power with minimum effort-and a low price in mind-the new EQ cylinder heads are available with 180cc, 200cc, 220cc, and 235cc intake runners, all with a 64cc combustion chamber and angle plug. With this wide range of intake runner sizes, EQ has the perfect budget head for any small-block Chevy engine, from 327 to 400-plus cubic inches.
All EQ 23-degree performance heads are also available in the smaller 50cc combustion chamber size to provide even more options for every engine builder and racer. The street price for a bare casting is around $300, or $400 assembled. These Australian-manufactured heads feature a thicker .4375-inch deck for greater strength, hardened DuraBond exhaust seats for improved durability, and phosphor bronze guides. With EQ's Australian-made advantage, the EQ 23-degree heads are pretty hard to beat for performance for the dollar.
The Chevy small-block engine has been the quintessential American performance engine for more than half a century, but it was replaced by the "LS" engine family in production vehicles more than a decade ago. That means the pool of rebuildable cores is shrinking. In many cases, you just can't be sure of the history of those remaining cores.
A reassuring alternative to rebuilding is a brand-new engine, and GM Performance Parts (GMPP) is the only source for all-new Chevy small-blocks. GMPP's crate engines use brand-new cylinder blocks, heads, and rotating assemblies-none of the components are reconditioned or machined. They also offer crucial advantages over old production engines, including the strength of four-bolt main bearing caps. Almost every used small-block core you'll find online, in a junkyard, or at a swap meet will have two-bolt mains.
GMPP small-blocks are an affordable alternative to building performance into a rebuild, as even the entry-level 350-290hp (shown, PN 12499529) engine delivers 290 hp and 332 lb-ft of torque. That's more than almost every small-block offered in cars or trucks from the early 1970s through the late 1990s, making it a great value-driven replacement for a 305-powered Monte Carlo or 350-powered truck. These crates are downright inexpensive too, for example, we found the 350-290hp engine offered for as low as $1,925 through Doylestown, Pennsylvania, dealer Fred Beans on GMPerformanceParts.com.
Rebuilding a small-block may be a time-honored tradition, but the stronger, more powerful, and affordable crate engines from GMPP are great options for enthusiasts looking to repower their project quickly-and without the nagging thoughts of the engine's history.

AMSOIL XL Synthetic
AMSOIL XL Synthetic Motor Oils employ an extra treatment of alkaline additives added to premium synthetic base stocks to neutralize acids. The extra additive package effectively raises the total base number (TBN) and resists shear to provide superior performance throughout the entire drain interval of up to 10,000 miles or six months, whichever comes first. Fuel-efficient AMSOIL XL Synthetic Motor Oils provide better fuel economy compared to conventional motor oils.
AMSOIL XL Synthetic Motor Oils are friendly to modern emission control systems and help maintain low emissions. Thermal breakdown effects including evaporation and viscosity loss are also significantly reduced, while providing excellent hot and cold engine protection. AMSOIL XL Synthetic Motor Oils are available in SAE 5W-20, 5W-30, 10W-30 and 10W-40 viscosities in quarts, gallons, 30- and 55-gallon drums, and 275-gallon totes.
New Valve Covers
Chevy and Ford owners can now upgrade their valve covers for less with Summit Racing die-cast logo valve covers. Available in hot orange or old-school black, the standard small- and big-block Chevy valve covers feature the popular Bow Tie emblem and lettering, while the Chevy 383 valve covers are emblazoned with "383 Stroker." The standard small Ford valve covers feature a classic finned design; the Ford 347 valve covers come in polished, black, or blue, and have a "347 Stroker" logo. (PN SUM-440408, $149.95, shown.) Summit Racing die-cast logo valve covers are crafted in the USA from high-grade aluminum that will clear most roller rockers, and they feature installed oil baffles.
