Wow, that reminds me: A friend had a 440 Challenger and it turned out there was an internal crack in the exhaust crossover from the crossover to the inside of the intake runner. When it got warmed up, the crack would enlarge and create an enormous internal vacuum leak, killing the engine.
Got any extra intakes?
