Having stripped out the old mechanics from the Grand National and meticulously cleaned, prepped, and painted the engine bay, the team now jumps on the task of preparing the supercharged LT4 for installation. However, before the new engine can find its place, a considerable amount of custom fabrication is required to ensure a proper fit.

Grimm takes charge of fabricating new motor mounts using the plasma table, while simultaneously addressing the intricacies of the cooling system. Kody focuses on preparing the engine itself, while Suppy handles the plumbing of the fuel system and installs the new fuel tank. To enhance the Grand National's under-hood aesthetics and functionality, carbon fiber fender liners are added. Angelo, showcasing some killer craftsmanship, them fabricates a standout component – the firewall cutout designed to accommodate the car's dry sump oiling system.

Episode 3 is coming at you with some pretty trick stuff, so sit back and enjoy because this is where things get serious!”
