In this video, the host is building a budget bracket race engine. They start with a Chevy small block, clearance it for a stroker crank, and replace the bolts with studs. They upgrade the camshaft to a hydraulic roller design from Comp Cams and set the cam gear. The main bearings are installed and checked for clearances, and adjustments are made as needed. The crankshaft is reused and balanced with ARP studs. They modify the oil passage for better flow, install the rear main, and check end plate clearance.
Next, they work on the cylinder heads, cleaning and lapping the valves, upgrading to beehive springs from Comp, and adding locator kits to prevent spring movement. The rocker arms are upgraded to Ultra Pro Magnum rocker arms from Comp, and they check the push rod length. The lifters and push rods are installed, and the engine is prepared with assembly lube and oil before installing the intake manifold.
The video also briefly shows the engine being moved to a dyno for testing and tuning. The host and team emphasize attention to detail and precision throughout the engine building process.
