Finnegan is back at it, in the garage and tearing stuff apart. This time it’s the 632 cubic inch Big Block Chevrolet that he broke. But what broke? Sometimes you tear up something so bad that you can’t tell what broke first, and sometimes you can get all CSI on it and figure out which thing ultimately gave up first before everything else went sideways. But other times you break things and the carnage isn’t bad at all. When this happens you might only have one broken thing to find. Other times it might be a couple things that seem unrelated and therefore are hard to diagnose.
In this video, Finnegan is going to see if he can figure out what broke first to cause his Big Block to die. Let’s see what he found.
Video Description:
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.
