What is this on this 2v Intake Mani?

[rackerm]

Never seen this on a 351C 2v Intake Mani before. Was it stock on some engines? The manifold is from a September built 1973 351C 2v engine. Looks like it connects the two water jackets on the back of the manifold, and what is the fitting for?

There's no water going thru a 351 Cleveland intake. That looks like a thermactor air pipe that's been thru a fire.

Thanks. I thought thermactor ports were on the heads. Never saw this before.

Rich, that's part of the thermactor emissions system (T/E) that started showing up on the 74 cars. That's basically a one year only tube on the 351C since the 351M replaced the 351C  in 75 and changed the way the T/E system was engineered. There was also a check valve in the top of the tube that is missing on that one. More "Stuff" that had a real good possibly of being "Trash Canned" once you got home! Lol

The engine block and heads the intake mani is on has a September 74 build, and from the serial number the block was assembled in Atlanta where the Torinos were assembled. So that all adds up.

Thank you.
