One simple mistake... and the Chevelle's engine was toast. If you've ever made a costly mistake in your garage build, you'll relate to this one. But instead of dwelling on what went wrong, we're going BIGGER. Way bigger.

This 1964 Chevelle engine failure taught me an expensive lesson about carburetor installation. Watch as I diagnose piston damage, cylinder scoring, and metal contamination throughout the small block Chevy.

🔧 WHAT'S NEXT: In the next video, we're taking this scrapyard 454 to BradFab's shop to see if we can get it running on a test stand before it goes into the Chevelle. Subscribe so you don't miss Part 2!
