I have a small block coupe with the 350 HP L79 motor and thought I read somewhere that there is supposed to be a windage tray aqnd trap door system with the oil pan. Can someone verify this one way or the other. Thanks in advance. Sheldon

Your L-79 engine should use a "5 quart" oil pan, originally GM #3820000 and ,later, GM #360866. This oil pan uses no external, upper baffle as you describe and is not equipped with an internal, "trap door" baffle.
The "6 quart" oil pan, originally GM #3820001 and, later, GM #359942 DOES use an external, upper baffle, GM #3769768. Also, this oil pan is equipped with a "trap door" internal baffle as you described. This oil pan was used on 63-65 Corvettes with mechanical lifter, small block engines and on 70-72 ZR-1-optioned cars. It cannot be used in conjunction with power steering, however.
There is an external, upper baffle that can be used with the "5 quart" oil pans, though. This baffle was used on 70-72 LT-1s (except ZR-1) with the 3820000 oil pan. This baffle was GM #3989075. Unfortunately, it is discontinued.In Appreciation of John Hinckley -

My '65 350 HP L79 has the 6 quart pan described by Joe. Are we sure only the 365 and 375 HP small blocks had the 6 quart pan?Comment

Re: WINDAGE TRAY ON 65 SB
Try Summit Racing or JEGs racing for the windage trays you seek. For SBC both a lifter gallery tray and an oil pan (crank stud) tray are available. These will work with your intake and 5 quart oil pan. They are essentially GM copies.Comment

As far as I know, the 6 quart pan was not originally used for 65 Corvettes with the L-79 engine. Here's what I believe confirms that: engine assemblies were received at the St. Louis Corvette plant with oil pans installed. Also, as far as I know, 1965 Corvettes with L-79 engines were available with N-40 power steering. So, if the "6 quart" pan were to be used for L-79s, there would need to be two different engine assemblies available: ones equipped with the "6 quart" pan for manual steering cars and ones equipped with the "5 quart" pan for power steering equipped cars. Furthermore, if there were to be such a difference, there would need to be different engine suffix codes so that the St. Louis workers could easily distinguish which engine needed to be installed in the vehicle. However, and as far as I know, for 1965 there were only four suffix codes used for L-79 engines: "HT" for L-79 with mt; "HU" for mt with a/c; "HV" for mt with TI; and "HW" for mt with a/c and TI. So, unless one of those combinations was "automatically" not available with power steering, there would be no way to differentiate a "5 quart" pan engine from a "6 quart"
For 1966 and 1967, though, there WERE different L-79 engine suffix codes used for p/s and non-p/s applications. Although I omitted this in my previous post, 1966 and 1967 L-79s WITHOUT p/s may have used the "6 quart" oil pan.
Of course, if your 1965 were a late-build, who knows? What is your engine suffix code?In Appreciation of John HinckleyComment
