500 fuel injection intake
I came across an intake for a 500 cid Cadillac with TBI.
The part number on it is 1615446.
None of my parts books have this listed, however my parts books go from 76-81 and 82-85.
Can anyone verify if this was for a mid'-75 TBI for 500cid?

Re: 500 fuel injection intake
Assuming that you meant to say EFI intake: I'm pretty sure that the 425 and 500 EFI intakes are the same beast. My intake was last used on a 500 but started life on a 1978 425. PN 1616059.
Your number does not show up in the bible here either. Chilton parts and time guide from 1984 lists my intake as 3516375 which isn't a match to the number on the manifold itself. We might be reading casting numbers which could be different from a part number.
There might be some difference in EGR setup but if it looks like a 500 intake then it should work. Other than that the paint color was different.
If you are dealing with a TBI intake then is has to be from a 1981 368 or later limo.
