2001 454MPI & 2001 350 carb.motors

[RMPRam]

I bought a 2001 454MPI motor to replace my 2001 350 carb. motor. The 454 came w/o the alt. sea-pump and PS pump and related brackets. My 350 has all these. My question is: will the brackets that mount these accessories on the 350, interchange to the 454 and will everything line up? Mine has the serpentine belt arrangement and i'm assuming the bracket bolting positions may be different? Anyone have any experience in case? Any help will be greatly appreciated. Thanks.

I believe most of the parts and brackets will work. The easist way to verify the interchange a ability is go to a mercruser dealer and cross check the parts list.
