The 1980 Seville has a V8 ,6.0l(368ci) engine; in fact a de-bored 425ci.Does engine parts of the 400 also fit the 368,for example if I want to change the valve covers ,oil pan,exhaust manifold,etc?I can't seem to find parts for the 368 engine.In fact the same for the TH 325 autom transmission,only parts from the TH425 seel to be available.

Here's parts for the TH325 trans: http://www.transmissionpartsusa.com/TH325_transmission_parts_s/733.htm

I do believe all the big block Cadillac engines have interchangeable parts as far as the bolt ons go. Might be slight differences in manifold configurations for different year emissions, but I'm pretty sure they're all close.
