I probably missed some stuff so it best to watch the video!

A 392 Stroker Kit for a 5.7L Hemi engine involves increasing the engine's displacement by installing aftermarket components to increase the stroke of the engine. This results in increased displacement, which can lead to improved horsepower and torque output. Here's how it typically works:

Increasing Stroke: The stock stroke of a 5.7L Hemi engine is around 3.578 inches. To create a 392 stroker, aftermarket crankshafts with a longer stroke are installed. These crankshafts typically have a stroke of around 4.00 inches or slightly more, increasing the engine's total displacement.

Piston and Rod Upgrades: Along with the new crankshaft, the engine will require compatible pistons and connecting rods to accommodate the increased stroke. These components are typically included in a stroker kit or purchased separately to match the specifications of the new crankshaft.

Engine Block Machining: Depending on the specific components used, the engine block may need to be machined to accommodate the larger crankshaft and associated components. This may include clearancing the block for the increased stroke and ensuring proper fitment of the new parts.

Balancing: After assembling the rotating assembly with the new crankshaft, pistons, and connecting rods, the entire assembly must be balanced to ensure smooth operation and reduce vibrations. This involves matching the weights of the various components to achieve proper balance.

Tuning and Upgrades: Once the 392 stroker kit is installed, the engine will require tuning to optimize performance. This may involve recalibrating the engine management system to accommodate the increased displacement and adjusting fuel and ignition timing for optimal performance.

Performance Gains: With a 392 stroker kit installed, the 5.7L Hemi engine can see significant increases in horsepower and torque output. The exact gains will depend on the specific components used, but it's not uncommon to see gains of 100+ horsepower over the stock engine.

Overall, a 392 stroker kit for a 5.7L Hemi engine can be a significant performance upgrade, providing increased power and torque for enthusiasts looking to extract more performance from their engine. However, it's essential to ensure proper installation and tuning to maximize performance and reliability. Additionally, be aware that modifications of this nature may impact warranty coverage and emissions compliance, so it's essential to consider these factors before proceeding with the upgrade.
