So when I got my '71 350/270 rebuilt and switched to a Performer Intake, the builder returned my original GM 3973469 intake manifold with a crack circled as shown below:
Crack appears to be in the crossover
I obviously don't need this anymore, but was curious if there's any reason to save this to pass along with the car when I (or an heir) sells it.
Or could it be of value to anyone looking for an original intake?
So that makes 2 boat anchors I have now, 1 exhaust manifold and 1 intake...

Yeah, I hear you guys about scrap, I was just curious if having the correct intake with the car, even if it was cracked, might "mean" something to a later owner. But now that I think about it, who really would care since it can't be reinstalled and used if they so desire?

If you had to run it there is block cement you can fill it with. I had some intakes I didnt want the heat travelling through so I filled them. Worked fine. THe cement is usually used in race engines to fill the bottom of the blocks water passages to stiffen the block and keep the cylinders from shifting
Looks to be on the underside and would be easily bronze brazed and undetectable once installed.
A correctly dated intake may be just what a restorer is looking for. Certainly not high dollar but could be perfect for someone.

Could each end of the crack be drilled-thru before being cemented or bronze- brazed???
