Why is it I cannot find a OEM replacement (new) intake manifold for my 1985 4.9L engine? I have found an Offenhauser polished aluminum intake, very expensive. I can find exhaust manifolds out the wazoo. What gives?
Yes. It cracked right where one of the bolts mount it to the head. Now at about 65 mph it wants to whistle. As soon as I slow down it stops or if I acclerate it stops only until I back off and the vacuum returns in the engine. Frustrating.
I bought one from the internet and was prepping it for installation and I found a big crack right in the collection chamber. They aren't that easy to R&R and I'm afraid to buy a used one and have the same problem. (See post #4)

850 horses. That's amazing! I would like to do that to my machine. I just love that 300 engine. People ask me what engine. I tell a six. They kind of go "oh". i don't thinkg realize it's an awful big six.
