Thinking of swapping my current 350 in my 70 Cutlass Supreme to a 455 that I just bought. My quetion is, are the accessory brackets the same on a small block that are on the 455? You now, ac, power steering. alt, etc?

 

I beleive they are, but you may need
longer belts with the 455.

 

Appreciate it.

 

Same brackets, but some will mount with different holes, due to the increased width.
