You’ve probably heard those Zen sayings that ask questions like, “What is the sound of one hand clapping?” or, “If a tree falls in the forest and no one hears it, does it make a sound?” Those particular questions may be a little weighty for the scope of this article, but Ford’s new Vehicle Personalization plan has us asking a few questions of our own.

When it comes to improving horsepower, one of the main names is Magna Charger. Long known for its supercharger systems for Chevy pickups and even hot rods, Magna Charger has more recently turned its attention to the Blue Oval. It was in late 2005 that the company introduced a system for the ’04-’06 Ford F-150 pickup truck equipped with the 5.4-liter Triton engine. Aiming to improve horsepower and torque in the 1,200-5,500-rpm range, Magna Charger chose to utilize its fifth-generation MP112 hybrid Roots-style supercharger system in this effort. The Gen 5 is equipped with an internal bypass valve, which the Magna Charger folks say reduces parasitic losses while cruising for increased efficiency and economy. Also, the Magna Charger system is intercooled, and everyone knows that cool air is denser than hot air, and denser air makes more power.

Grand Spaulding Dodge in Chicago became known as the world headquarters for great deals on new Dodge performance cars. This dealership fully dyno-tuned the performance cars it sold and often equipped them, as requested by the customer, with headers, bigger carburetion and other go-fast engine modifications—all right from the dealer.

Introduction to the Project ’47 Chevrolet Pickup

Previously, we introduced the Street Rod Headquarters and Chevs of the 40’s project ’47 Chevrolet pickup. To quickly recap the build, owner Rob Logsdon purchased a well-worn ’47 Chevrolet truck from a farmer’s field for $100. From there, a Corvette C4 front and rear suspension were located for an additional $2,500, and both the truck and the suspension components were then delivered to Time Machines Northwest.

The Vision: Building the Ultimate Show Truck

Logsdon’s concept for the pickup is to build the ultimate show truck to showcase many of the parts available for the very popular ’47-’53 Chevy trucks. Since this will be the company truck, the plan was to use as many aftermarket components as possible to show fellow truckers what is available. To date, the truck has received the C4 Corvette front and rear suspension utilizing Flat Out Engineering components and a custom aluminum fuel tank. The chassis was powder-coated and features an impressive Blueprint Engines 383ci engine.

Engine Choice: Blueprint Engines 383 Stroker Motor

If you caught the completed chassis story, you may have noticed the beautifully detailed small block sitting between the framerails. During the chassis build, Logsdon decided that the 383 Blueprint Engines stroker motor was the way to go, and as a direct retailer for Blueprint Engines, his decision was a no-brainer and made sense. After all, these engines are professionally hand-built and feature a 30-month, 50,000-mile warranty. The Blueprint 383 provides the Advanced Design pickup with nearly 400 hp and 442 lb-ft of torque, which is plenty of power for cruising, especially the fairgrounds.

The Engine Build: From Machining to Assembly

During the engine build, Blueprint Engines took the time to photograph the machining process, as the company completely refurbished the Chevy four-bolt main block, machined, and assembled it into a brand new horsepower monster (see sidebar for engine specs).

Top-End Assembly and Aftermarket Components

After receiving the Blueprint small block, Chevs of the 40’s quickly began assembling the top end of the engine before paint to trial fit the aftermarket components to ensure proper fitment. Rather than try to piece together a drive system, Logsdon decided to use a Billet Specialties Tru Trac. The Tru Trac will provide the truck with the needed accessories as well as all the brackets and pulleys, plus it looks great and dresses up the front of the engine.

Fuel Delivery System and Transmission Installation

Street Rod Headquarters then tackled the fuel delivery system. Blueprint Engines offers only a single four-barrel combination, but Logsdon decided to swap out the single carb for the Barry Grant Six Shooter. The Six Shooter package is comprised of an aluminum intake that mounts three 250cfm Barry Grant carbs designed with the center carb being the primary carb. The front and rear carbs are operated via progressive linkage. After bolting on the fuel delivery system, the last thing left was the addition of the Sanderson block hugger headers and the 4L60E transmission.

Final Assembly: Painting and Installing the Engine

Before installing the engine and transmission, the entire engine was stripped of all its accessories and painted a light silver to match the framerails. When dry, the crew at Time Machines Northwest reassembled the engine, bolted on the transmission, and installed the assembly into the freshly powder-coated framerails. With the chassis and drivetrain complete, we now move on next issue to cover the sheetmetal and body restoration, as Time Machines Northwest works its magic on this time-worn pickup body.

For now, follow along as Blueprint Engines builds a 383 stroker from the ground up.

2. After the machining process, the block is then pressure-checked to ensure there are no weak spots or cracks, as part of the sonic testing of cylinder wall thickness.

3. Decking of the block is where the deck surfaces on all Blueprint blocks are machined to ensure a leak-free seal for the cylinder heads.

4. Measuring of the deck height is part of the blueprinting process, this procedure checks the distance from the crank centerline to the top of the deck (head surface). It is checked at dif-ferent locations—front and rear—on the deck surface to ensure it is parallel to the crank centerline.

5-7. After boring, each cylinder hole in the block is honed to achieve the final finish and size for each cylinder. The proper finish and straight hole will allow the piston rings to seat correctly and the engine to seal properly.
