Bobby Oberlander turned to ModMax when he wanted to build up his dream Mustang and needed the right parts for his engine combination. His 4.6 Boss Block has a 3.700" bore that is combined with a 3.800" stroke for 324ci. With his turbocharger and other goodies he has been able to get 879 horsepower and 1000 ft/lbs of torque from his toy. Glad we were able to come up with a custom Diamond Piston to work with his boost and E85 with double coatings, upgraded Heavy Wall pins, and other various engine goodies to finish out his build. His car was featured recently in Muscle Mustangs and Fast Fords. Here is an excerpt from the article:

Oberlander acquired a Ford Racing Boss 5.0 modular block and dropped it off, along with all rotating parts and pieces with Todd Maschmeir out of Oak Grove, Missouri, to be machined and assembled. Once the short block was back in Oberlander’s hands, he and friend Welch assembled the top end with a pair of Ed’s Speed Shop Stage 3 CNC cylinder heads and custom cams, a Ford Racing intake and throttle body, and MSD coil packs. Oberlander took his time breaking in the new engine before going in for a custom tune. The Three-Valve boasts 326 ci with a Kellogg crankshaft, Manley Performance H-beam connecting rods, Diamond 2618 pistons, and ARP hardware. Oberlander’s GT makes envy-inducing horsepower thanks to an On3 Performance single 70mm turbo with a 50mm blow-off valve, and a 38mm wastegate.

NEW!! Coyote 5.0L Forged Ross Pistons 4cc DOME with Rings 4.6 and 5.4 Forged Probe SRS Pistons 18cc Dished COATED CHROME 3-VALVE CAM COVERS 4.6 / 5.4 ARP - The world leader in fastener technology has just released five new Pro Series main cap side bolt kits for Ford Modular 4.6L & 5.4L V8 applications. All Pro Series side bolt kits feature 8740 chrome moly steel 12 point bolts that are heat treated prior to thread rolling and machining, and are nominally rated at 200,000 psi. Special purpose washers are included where necessary. Optimum design, enhanced reliability and increased strength are the main attributes of ARP’s Pro Series main cap side bolt kits.

Factory side bolts are torque to yield design and must be replaced when rebuilding as they are not reusable. These high quality ARP side bolts are designed to be used over and over again, plus will offer the best clamping forces for high performance engines. Sold in complete sets for one engine.
