    Super stoked I found this oil pan. At the time of writing this review there are none in stock anywhere. (Rona-shortages) good quality thick steel. However. Make sure you check all clearances, all! I check the oil pick up and had to make some custom cuts. I hand turned the motor and that sounded fine. But once all back together, I fired it up and something was knocking on my oil pan! The crank was hitting the baffle in the pan. Had to pull the motor and drop the pan, again.

    Put it in my jet boat and goes great. For the cost. Holds enough oil to keep my 455 oiled up without sucking the pan dry
