408 Ford Long Block
Looking to keep your original transmission and perhaps even use your factory EFI? This 408 Ford is an excellent choice as we use a much milder camshaft and you can use your factory intake to be SMOG friendly with the factory EFI system and E40D transmission. Simple injector upgrade and a basic tune should get it rolling in the most inexpensive manner. The condition and reliability of the transmission is unknown therefore it is in the best interest to have it rebuilt or gone through with a potential converter upgrade. Features forged pistons, hydraulic roller camshaft, and aluminum heads.

Dyno Testing
Dyno testing not included in long block price. Here at Prestige Motorsports, our “Dyno Promise” means that we dyno test every engine we build to verify the quality of our work, the integrity of each component, and the reliability of every engine we construct. Then, we deliver the dyno results for your project directly to you, the customer. Hours for dyno testing will be calculated with the purchase of the fuel and ignition group per engine order.
Engines will produce +/- 2% of advertised power at the flywheel. Advertised power levels are achieved using an electric water pump and specific induction and exhaust systems. Power will vary after pulley systems are installed or if changes are made to the induction or exhaust system (e.g. camshaft, cylinder head, compression, intake manifold, exhaust headers, air filters, etc.). Chassis dyno results measure power at the wheels and only calculate flywheel horsepower. Wheel horsepower is affected by a variety of vehicle-specific criteria including driveline design, body and chassis flex, air intake location, etc. Therefore, calculating flywheel horsepower from wheel horsepower is not an accurate representation of actual flywheel horsepower.

Warranty
This Prestige Motorsports engine is built to order and comes with a 3-year, unlimited miles warranty. Our warranty covers the base engine from intake manifold to oil pan.
