    12568774 is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from Great swap Installed in a 69 el Camino about a year ago. Runs strong and with abou 2000 miles hasn’t used any oil.
    Date published: 2018-02-04
    Rated 1 out of 5 by from JUNK! Thinking of spending the extra money on a GM engine for piece of mind? Think again! Our engine failed after 4.5 hours of operation. Jegs and GM offered us nothing in return. I would give the engine "0" stars if it were an option. Buy from a different manufacture elsewhere.

    I’ve got a 1970 Chevy el Camino what oil pan do I need for this motor to fit ?

    Asked by: 454 Dave
    You will need to determine the oil pan needed as this is not made for the El Camino chassis.
