I Sherlock'd My Dead Big Block Chevy and Found Out Why It Broke!

Подробнее о видео

Episode 282 of Finnegan's Garage is all about discovery how and why my all-aluminum 632ci Big Block Chevy Nitrous Motor broke during the World Finals of Drag Boat Racing last November. It was a disappointing racing weekend to say the least. We travelled from Georgia to Arizona with high hopes that we could be competitive in two different racing classes. Instead of running with the big dogs we struggled to go as fast as we had in the past when this engine was naturally aspirated. After hours of disassembling the engine, carefully measuring and staring at parts, now we know what happened. Check it out.
