    I had a 74 DartSport back in 77/78ish, with a 360-4gear. I really liked that car. And I really liked the TQ moan; sometimes I really miss it. The moan I mean, not the car,lol.

    I don't think the 360 came with a 4-bbl until '74 (after 340 production stopped in '73) – but could be wrong.
    '73 340's and all 360's came with cast crankshafts – so would have a externally balanced balancer and flywheel – but both engines will have different balances.
    If a '72-3 340 – the balancer will have 340 cast on it, so a person can take a camera and take a couple pictures around (front side) perimeter and look for the “340”.

    I “think” both versions of the flywheel might also have engine size cast into it (“340” or “360” ) - but again, might be wrong. The Flywheel will be harder to determine.

    My Mopar engine book says the L code 360 was a 73/74 product, there was also a 340.

    The 360-4v was introduced in 73, but didn't start replacing the 340 in the performance models until nearly the end of 73 production. There is at least one 360-4v '73 'cuda built. Orange dual snorkle cleaners showed up on some early '74 Chargers with the 360-4v.

    Because of emissions, I “think” the 340 didn't make it through the full year ('73) – but I have absolutely no information to prove or disprove.
    I do remember the 360 was 2-bbl only until the 340 was out of production – even though both used same cylinder heads.

    It could be that 340 orders were filled 360s at the end of 73 production or an early 74 got a 73 air cleaner. Ho knows?
    But I've gotten curious and I'm going to find the VIN..
