Building a 355ci Street Stock Engine for Dirt Track Racing!

We’re building a dirt oval track street stock engine from the ground up — 355 cubic inches of reliable power, built to the rule book. In this first part, we assemble the short block using high-quality components like a Molnar crank and rods, Mahle pistons, and a custom Comp Cams flat tappet camshaft. Built for a class-legal setup using factory Vortec heads and a Holley 4412 2-barrel carb. This is a no-nonsense street stock build for competitive dirt track racing. Part 2 will finish the top end and go for the first fire-up! 🛠 Engine Specs: – 355 cubic inches – Molnar crankshaft & rods – Mahle pistons – Custom-ground flat tappet cam (Comp Cams) – Factory Vortec heads – Holley 4412 2-barrel carb 🔥 Support the channel and grab some gear: https://youngbloodperformance.com #StreetStock #DirtTrackRacing #360SBC #EngineBuild #OvalTrack
