SCIENCE! I FINALLY GOT MY 10.3L V8 JET BOAT RUNNING RIGHT!

Episode 410 of Finnegan's Garage has us deep diving into modifying the Holley Gen 3 Dominator carburetors on my jet boat. In this video we go over how to read spark plugs, how to analyze data to make tune decisions, and in the end we find out the right combination of parts to make this 632ci Big Block Chevy V8 run right.
