CFE SBX-Asymmetrical "Small - Block - Experimental"

Since the beginning engine builders have put their skills on the line, determined to make more and more power. Determined to milk every last once of horsepower from their small blocks. The existing racing head technology of the day would have no part in this escapade and often lead to engine builders flat-out giving up on the small block. The CFE Little Chief is the solution to the power deficit that many small block engine builders face. It is the only racing head in existence (with exception to it's evil twin "The SBX-Symmetrical") capable of adequately feeding a 450+ cubic inch small block and generating over 1000 horsepower.

The drought is over, The CFE Little Chief is here and available for your engine program now. CFE has application specific CNC programs for turbo-charged, super-charged, nitrous oxide, and naturally aspirated applications. Your competitive nature won't let you be second best so why invest in inferior racing head technology. Don't be sent home early only to ponder your investment in our competitiors technology, get the real deal. CFE has over 25 years of experience developing racing heads for hardcore racing applications just like yours. Call us today at 586.773.6310 for more information.

The new CFE SBX lineup incorporates many improvements and features that were previousley unavailable including:
• a symmetrical-intake-port version, "The SBX-Symmetrical" that favors two carburetors and allows the racing heads to be used on a standard small block with conventional lifter bore locations. This negates the need for custom blocks and special cam cores.(For more information on this version click here.
• Both versions sport a greatly improved rocker bar platform, structurally engineered to handle abusive environments and increase valve train stability.
• An extensive set of power proven intake and exhaust valve combinations have been added including a 2.250 by 1.600 arrangement for large bore applications.
• The CFE SBX series of racing heads are available in either Pro or Sportsman trim, allowing the racer and/or engine builder to choose the price performance level that fits their racing program best. All CFE SBX racing heads regardless of trim level includes CFE's Signature application specific cnc porting, world class craftsmanship and industry leading port-to-port consistency.

CFE Little Chief Details:

The CFE Little Chief is basically a small block version of a big chief head. It requires a Little Chief cam core and a block with custom lifter bore locations. The intake port layout is asymmetrical. The symmetrical exhaust port layout eliminates the Siamese exhaust-port hot spot encountered with conventional SBC heads. Extra material cast onto the top of the CFE Little Chief makes for a stable rocker stand platform to eliminate flex, fatigue and ultimately failure seen from other castings exposed to today’s high spring pressures. An extra thick deck surface provides durability under high cylinder pressure and an excellent head gasket sealing surface.

• 11 degree normally aspirated (40cc combustion chambers)
• 11 degree turbo specials (69cc )
• 15 degree nitrous specials (68cc)
