    It doesnt have that winged out oil pan, it has a hump at the rear end of engine like a normal style oil pan.

    Then it's NOT out of a Corvette.
    Probably out of an F-body, But since it has 241 heads it's an `01-04 spec LS1.

    So even with the 241 heads it has to be an 01-04 LS1 Is that when they started making them? Or did vette start earlier? Thanks

    There are some late 2000 cars (Vette and F-body) that had 241 heads.
    Thing to look for is whether the car had an EGR valves mounted to the front passenger side head. You should see evidence of the mounting bracket being there. If it has this then it would be a late 2000 F-body engine AFAIK.
