Need help decoding, just pulled the engine and trans from my 65 Chevelle

block #is 3855961 65=66 396 as expected.

the trans looks like a t-10, numbers are as follows

13-04-066-903 F3077

13-04-097-901

any help would be great, if you need more info let me know...Dave

Dave, looks like you probably have a 1977 Borg Warner 4 speed there. CBTN only goes to 1975, but 1974 and 1975 Borg Warner 4 speeds have similar numbers (1304 065 903 and 13.04.066.901). If the F3077 is a date code, it wouild be June 30th, 1977.

Thanks Ed, my frame is at the powdercoat shop in Riverside, and I need to get busy getting the engine and trans ready for it. Now I need a tranny shop to rebuild it....I can do autos but never done a 4-speed...
