    Oil Pan Identification

    No picture, just words and measurements. This is a three level pan stepping down from 1 to 3 and all measurements are from the front unless otherwise noted. 1st step starts slope down to #2 at about 3 1/2" and 2nd step is level at about 5 3/4"; slope down to #3 begins at about 12" and this slope is "steeper" than that from 1 to 2; step 3 is level at 14" and extends 8". Drain hole is centered in the middle and 3" from the BACK.
    On the underside, the pan has two deep wrinkles on each side where it goes from step 2 to step 3.
    On both sides, there are two 1" long depressions where it goes from step 2 to step 3.
    On both sides, there is one 6 1/2" long depression in the approximate center of step 3.
    Back of the pan has wrinkles in no discernible pattern.
    No trap door, just forward baffle in front of oil pickup area.
    Is this #3789629 pan that appears in the October 1961 Parts Book out of nowhere and is declared for 57-62 or ??????

    Re: Oil Pan Identification

    Lorn,
    Based on your comment of "two deep wrinkles between step two and three," that sounds like oil pan part number 3735640. The explanation (I have) of 640 states "this pan has two recess areas on the second step of the pan." Late '56's Corvettes and '57 passenger cars supposely used this pan. My mid-'56 oil pan does not have this recess area and was a three step pan. Hope some of this help. Regards,

      Loren:

      I have a late 56 pan with no wrinkles. I do know that the pan you described was used on 56 passenger 265's with the power pack option.

          Loren:

          My car is #4200 and I believe that Jim has a late one also. The middle 56's is an arbitrary number.

              I have serial number E56S002653. Which may have been built on May 25th. AS this approaches 50% of '56 production is this a late car in terms of heads, manifolds, and carbs? Or still among the early?

                  Dan,
                  Thanks for your question. Early 1956 cars are conidered to be in the first 700 of production. As a point of interest I have '56 serial #2675. If you get a chance the Ontario NCRS AGM is Sunday.

                    Scott is that as in.....

                    ....sequential number 1675? Further would that be the red one or the black one?

                    I see serial 2676 (#1676) was a Canadian sold car.

                    I'll try to make it out to your meeting.
