Dixon survived massive Top Fuel shunt

Larry Dixon’s recent spectacular crash during the NHRA Gator Nationals in Florida last month wasn’t his first encounter with a dragster falling apart. Though alarming he was fortunate his skyward wreck landed inside the track wall where it skidded to a halt and not in the unforgiving earth beyond the wall. Watch: https://www.youtube.com/watch?v=e0xVHPiKRec Images: http://markjrebilas.com/blog/?p=21971#more-21971 Dixon (48) is a formidable NHRA Top Fuel contestant.

Big-Block Chevrolet: World Product’s Merlin III Adds Deck Height

Big-Block Chevrolet: World Product’s Merlin III Adds Deck Height

World Products American-made Merlin III cast-iron big block is now available with an extra .050″ of deck height. For the Chevrolet, 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...

New head gaskets for racing engines

New head gaskets for racing engines

By Titus Bloom:   Two months ago, in February 2015, JE has announced a new range of multi-layer steel (MLS) cylinder head gaskets for high-performance and racing engines. They are called the JE Pro Series. Originating at the turn of the nineteen-nineties, the unorthodox MLS gasket shook the establishment. Complex and revolutionary by comparison to its forerunner, its fundamental difference was its multi-layer construction—usually consisting of at least three layers. Kentucky-based World Products engine designer, Dick Boyer, says “MLS offer several significant advantages, particularly when situated between two different materials. Dissimilar metals, like a cast-iron block and cast aluminum cylinder head, for example, expand at different rates and the MLS gasket allows more movement than the conventional-style head gasket, because of its multi layer construction.” The conventional gasket is typically composed of a single steel core with paper gasket material attached. The inner portion of the MLS, which is made of stainless steel, serves to provide the finished gasket thickness. It also acts as the layer on which the top and bottom layers press against and, importantly, it contributes to the gasket’s sealing properties. The outer layers, which are also made of tempered stainless steel, feature raised beads or embossments that encircle critical sealing areas particularly the combustion openings and water jacket ports. The spring steel raised beads of the upper and lower layers resist flattening and it is this spring pressure that creates the seal, particularly when the engine is operating. Race engine builder Jon Kaase refers to the unique quality of the MLS gasket as “its springiness”. Unlike the conventional gasket, which cannot expand and contract, the...
