Fuelab 585xx Series Fuel Pressure Regulators Provide Racers with Ultimate Performance and Reliability

Fuelab, the leaders in fuel delivery innovation, announce their latest development in superior fuel pressure regulator performance and reliability. Fuelab 585xx Series Fuel Pressure Regulators combine advanced features and increased functionality to provide the ultimate precision instrument for fuel pressure regulation.

The four outlet port regulators are engineered to deliver extremely high flow rates and a flattened curve for pressure stability. Featuring an anodized billet aluminum body, the regulators use an aerospace poppet valve design to provide smooth regulating capability and maximized flow. They operate within a 4-10 psi pressure range, and an adjustment mechanism with fine thread pitch allows for precise fuel pressure adjustment. A methanol and E85 compatible soft seat avoids fuel pressure creep. This main seat assembly can be quickly exchanged in case of seat damage such as debris, and can be disassembled for replacement of the o-rings in the soft-seat design.  Features dual 10AN inlet ports, and four 6AN outlet ports arranged inline for cleaner installation, and with port spread that allows for smooth fuel flow when using an 8AN line size. Fuelab 585xx Series Fuel Pressure Regulators are perfect for single stage and multi-stage nitrous applications, and are compatible with gas, diesel, methanol and E85 fuels.

World Products Merlin III Block with Added Deck Height

World Products American made Merlin III cast iron big block is now available with an extra .050" of deck height. This new feature allows greater versatility in selecting connecting rods and particularly in selecting pistons with additional compression height to keep the ring grooves and wrist pin bore isolated.

The new Merlin III variant is available with a 9.850" or 10.250" deck height. Cylinder bores are semi-finished at 4.595" allowing for a finish hone to suit the specific pistons and ring packages chosen by the engine builder. Cylinders can be safely bored to 4.625" and with minor clearance the 9.850" deck Merlin can accept up to a 4.375" stroke crankshaft and the 10.250" deck can accept up to a 4.750" stroke. Nodular iron 4-bolt main caps are used with ARP fasteners for maximum strength.

The Merlin III is cast from high strength iron alloy and precision machined on CNC machining centers for dimensional accuracy. World's priority main oiling system delivers lubrication to the critical main bearings first for reliability at high rpm.
Head bolt holes are blind tapped and do not go through into the water jackets. The valley has bosses machined for four extra head bolts to accommodate race heads which utilize this feature. The oil pan rails are machined to accept both stock pans and aftermarket race pans.  World's Merlin III big block is an ideal choice for a wide range of performance engine configurations.

Part numbers for the upgraded blocks are:
081107  MERLIN III bare block,    9.850" x 4.495" Nodular splayed 4-bolt caps
081117  MERLIN III bare block,  10.250" x 4.595" Nodular splayed 4-bolt caps

Like all World's blocks and heads, The Merlin III is 100% American made. World blocks are cast from high-strength iron alloys and are precision machined on CNC machining centers for unmatched accuracy. World's new digital inspection equipment and quality verification procedures ensure dimensional accuracy and mean you can be assured of total quality and superior performance.
