Can anyone identify this intake manifold?

They are both Aluminum Intakes. one on the right is from a 69 427 but the one on the left has no stamps and the ports are larger and not aligned to the other one. Is it a 454 Aluminum intake? Manufacture?
thanks

Waaaaay above my level of knowledge. You might want to post the question on the C3 section of the forum. Those guys are pretty savvy when it comes to the C3.

Or see if X-Fire knows as he is knowledgeable in a lot of the older era engine parts.

Thanks i will check with him.
The unknown one is just slightly different in its alignment and port size compared to the GM 801 which is the original intake for 69 427.
My guess is that this is for a 454 but Aluminum?

XFIRE hasn't been back here for over a year so may not answer.
