383 vs 360 in an A 68 Cuda

What are the intake and exhaust manifolds? Is the left side exhaust an M-Code manifold, a 383 or something else? Does the air cleaner have a drop base? I really like it.
Thanks!

Those exhaust manifolds were B body HPs. from what I remember 1971 manifolds. Intake was an RPM with a drop base air cleaner
