    Default 345 or 392?

    I just picked up a scout motor with a 4bbl intake on it and the serial ID numbers read: 242544 with an "A" stamped slightly above it. This is located just above the passenger side motor mount. How do I cross reference these numbers? thanks

    I don't have the number guide handy, but on the pad where the serial number is, there is an engine size as well.

    The scout did not come stock with a 392. somebody would have had to swap it in. The 345A would be a stock engine for a 79-80 scout, and it would have come with a 4 barrel. If it is an original scout engine, it is a 345.
