| | | | Joined: Dec 2007 Posts: 140 'Bolter | | 'Bolter Joined: Dec 2007 Posts: 140 | I took a GMC 270 out of a 1951 Chevy COE and it appears to have the GMC intake/exhaust setup. I've tried to identify the exhaust manifold # but can't find it (or even one similar) anywhere. Typically I can at least find a part # on gmpartswiki but even wildcard searches come up empty. 2090603 is my best guess at the exhaust casting #. Curious if anyone else has run into this. I'd upload a picture, but I'm having trouble finding where / how. Thx for any help you can provide.

While it will not give part # it will give an idea what others have.
Here is a Stock GMC 228 manifold which I think is a shared part with the 270 ?

What is the question? | | | | | Joined: Dec 2007 Posts: 140 'Bolter | | 'Bolter Joined: Dec 2007 Posts: 140 | Whether or not 2090603 is a legitimate part number | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Forging numbers and part numbers are seldom the same.
Often the part number is one number off from the casting number.

If you PM me I can text you a picture of the parts book listing.
