Ep 88. AMC 401 V-8 Racing Engine Build! High Revs! Big Power! Trans-Am Killer!

In Hot Rod Garage season 8 episode 88, the team of expert mechanics is excited to dive straight into building an AMC 401 V-8 racing engine. With high revs and big power output, this engine has the potential to dominate on the racetrack. The team plans to install it in a classic muscle car and make it a Trans-Am killer.

The episode begins with Tony Angelo and Lucky Costa breaking down the AMC 401 V-8 engine. They explain in detail the various components of the engine and how they work together to create the desired output. They also talk about the benefits of using this particular engine in a racing car and how it compares to similar engines in the market.

The team then moves on to building the engine, starting with the camshaft. They explain how the camshaft affects the valve timing and how it can be adjusted to optimize the engine's performance. They also install new lifters and pushrods to ensure smooth operation and maximum power output.

The next step is to install the timing chain and gear, which is critical for proper engine timing. The team pays close attention to the alignment of the camshaft and crankshaft gears to ensure that everything runs smoothly without any interference. They also install a new timing cover and water pump to keep the engine cool during high-performance use.

With the timing chain and gear installed, the team moves on to the cylinder heads. They explain how porting and polishing can significantly improve airflow and power output. Lucky Costa uses a CNC machine to accurately shape the ports and polish them to a mirror-like finish.

The team then installs a new set of valves and valve springs to ensure proper operation at high RPM levels. They also measure the compression ratio to ensure that it's within the desired range for maximum power without risking engine damage.

Next up is the installation of the intake manifold and carburetor. The team chooses a high-performance intake manifold that is optimized for high RPMs and installs an appropriately sized carburetor to provide the engine with the necessary air and fuel mixture.

Finally, the team installs the MSD ignition system, which is designed to provide optimal spark timing and power delivery at high RPMs. They also install the headers and exhaust system, which is designed to provide the engine with maximum flow and minimal backpressure.

With the engine assembly complete, the team tests it on a dynamometer to measure its power output. They are pleased to see that it produces an impressive amount of horsepower and torque, making it the perfect engine for a Trans-Am killer.

The episode ends with the team installing the engine in a classic muscle car and taking it for a test drive on the racetrack. The engine performs flawlessly, delivering high revs and big power, just as promised. The team is thrilled with the results and confident that this engine will dominate on the racetrack.
