What's hiding under there? 🤔 Just another motor being built from scratch in house for you! 🚗 In the pic, we've got the engine block chillin' on an engine dolly, because let's be real, it's way easier to spin it around the crankshaft when adding new parts 🔄. Oh, and check out those two connecting rods already hanging out with the crankshaft - they're like the ultimate BFFs 💕
