I assume the brackets on a 350 would be the same on a 455. But i have my 350 and it looks nothing like these brackets i have for the 455.(i'm at work and won't have pics till tonight). Can someone pls post pics of the brackets on a 455. Thanks

 

All 1968-1976 350 brackets also fit the 455. Late 70s 350 brackets do not. Be aware that A/C and non-A/C brackets are completely different. Is that possibly your problem?

 

I sold the 350 to build my 455 and never actually ran the numbers on it to know what year it is. So that could possibly be my issue. I sold it to my cousin so i still have it and i'll run the numbers tonight but let me ask this also while where on this subject would the power steering pump bracket bolt up to the same water pump bolts like it did on the 350? or does the same apply?

 

That will be the same. The bottom end on all of the "modern" (64-90 except the 394) olds blocks are all the same.

 

Correct, though just to clarify, all the 1968-1990 PS pump brackets are interchangeable. They may not be visually identical, but they all bolt up the same and put the pump in the same place. The 64-67 brackets are different because the pump sits high on the driver's side.

 

ok well i'm going to come back tomorrow with pics of the brackets i have for the BBO. Because i sat out last night and tried every possible way to see how and where they bolt up but i couldn't come up with it for the life of me. Thanks guys
