Hola Jim
Every Imperial made starting with the 1959 production year until the last
one went out the door in 1966 ( I mean 1978 ) had the 413 and then a
440. If you truly have an 383 cubed engine, it is cause the original one
went bye-bye.
I understand that things do happen in time. Sooo, the answer to your
question is: any exhaust manifold from the left hand ( aka drivers
side ) from 1959 to 1966 will fit if it is from an Imperial ( 413 or 440
). If it is an 361, 383,413, 426 wedge or 440 from an lower division of
MoPar and has the center dump exhaust manifold, it to will work.
If you are think this may be a good time to do an "retro-fit" and gain
some quick power by using one of the HP exhaust manifolds made from 1968 to 1978
that was on GTX's, RoadRunner's, Crashielr 300's and some more, do not
waste your cash on any manifold from any spec'd whatever of these car's cause
they will not fit/clear your ( or any 1959-1966 ) Imperial on the left
side.
From the 1972 to 1978 Dodge Truck Division there is an HP center dump
Exhaust Manifold. It will add more power and appear as if it was placed
there by an Imperial worker in 1960. Both sides dump in the center and it
will fit with out taking classes to learn how to get it to fit.
