I need to replace my intake manifold due to corrosion and am struggling to find an affordable replacement part. 811575 is the part number listed. I have found a lot of them with oval ports but mine has rectangular. I am curious if anyone knows of any other intakes that might be compatible so I can add that to my search. I have found a few that are new but they are over $800 and the oval port versions seem to be selling on ebay for under $400. Any help would be appreciated.

Look for "marine BBC intake"
You will find them for less

If your in salt, look for cast iron 502 marine intake manifold

Or just cast iron 502
