Hoses would be same. The 403 the same as a 350 that the Olds engineers modified the block w/ siamesed cylinder bores to allow a much bigger bore. I am sure the filters are same, but will get back to you...for sure

Pontiac and Olds engines use different size filters, different part numbers.

Well,
I was shooting from the hip, I sold auto parts from 1985-1998. If you have a true Pontiac, Olds, Buick, or Cadillac engine, a true to brand engine , not a corporate swap... 1960-1967 or 68 all those makes use the Wix 51049, the long, wide filter... 1968-1978 all those makes use the Wix 51258, the short wide filter. Wix 51045 is the long narrow filter that can be used in place of one of those Wix 51042 is the short narrow that can be used in place of one of those The narrow filters seem to cause possible flow restriction problems, as many have stated here, when used in place of the wider filter numbers. There's also a late model GM filter that will fit a Pontiac, although it would be classified as a long, narrow filter, Wix 51522, It does however have an anti drain back valve in it.. Maybe other brands have different part numbers specific to certain applications. Just telling what I know............

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
