    63 shp oil pan

    Anyone have a picture of the 63 six quart oil pan as I see different placement of the drain plug. Thanks in advance.

    Doesn't show the drain plug, but here's a pic of me, back in late 1977 (when I had almost all my hair), spraying my 63 FI block. I believe original oil pan, and if it's the same as the '64-5 hp pans, the drain is about the middle of the back.

      The oil pan in Wayne's photo appears to be an original to me. The original GM part # is 3820001 (63-65 Corvette w/SHP, FI) and was replaced by GM # 3956670 in June 1970 and then replaced with GM # 359942 about 1977. The 359942 oil pan is similar to the 3820001 oil pan except for the front seal area. The oil pans made in 1975 and later use a thick front seal (0.41") while oil pans made in 1974 and prior use the thin front seal (0.22").

      My 1972 Corvette Parts Catalog (Sept. 1971) list the 3956670 oil pan for 69-72 Corvettes w/SHP (350) as well as a replacement for 63-65 Corvettes w/SHP, FI. I do not know the difference between the 3956670 oil pan and the 3820001 oil pan but I believe that the 3956670 pan was redesigned because of a clearance problem on 70-72 Corvettes w/SHP with the power steering equipment, but I may be wrong. Both of these pans would use the thin seal (0.22").

      My 1969 Corvette Parts Catalog (Oct. 1969) and my 1969 Chevrolet Parts Catalog (May 1969) do not list an oil pan for the 69 Corvette w/SHP (350).

        I believe that the difference between the 3820001 oil pan (top photo) and the NOS 3956670 oil pan (bottom photo) in the front "nose". The front "nose" on a 3820001 is basically parallel with the block mounting surface while the front "nose" of a 3956670 is not (redesigned for power steering equipment clearance purposes, I assume). Because of this volume of the 3956670 and 359942 pans would be very slightly less than the 3820001 oil pan. Does anyone has a better photo of a 3956670 or 359942 oil pan for comparison purposes to the top photo?

          There was no 1969 Corvette with a 350 SHP. For 1969 there was only the base engine and the 350 HP (i.e. L-46).

            I really can't see a difference but it's hard to compare from the photos. However, there's no reason that the "6 quart" pan would have needed to be modified for power steering applications as the 6 quart pan was never used for a power steering application. For 1970-72 LT-1, the 6 quart pan was only used for some 1970 LT-1 (cars WITHOUT power steering) and all ZR-1 which was not available with power steering. So, there would have been no need for a revised 6 quart pan for power steering applications.
