I have an intake manifold, cast iron, with an "M" cast on the body. Does this have any significance? I was told it was a higher volume intake but don't really know. Thanks for any input.. John

How about a picture?

Not at the moment but externally it looks like any other manifold. The inside of the casting seems to be slightly cleaner, that's all

Does it look like this? This one has a pipe plug in it. Above that is the letter "M"? I always thought it was an "E" turned sideways.

Maybe it was just an identification of what wooden casting pattern was used - they were using several in parallel and had to be able to identify which one that might be worn / damaged in case of bad castings starting to appear.

I have one with "M" (for Mark LOL) and Ford script cast in it. For the most part, what Roger said.

Read down close to bottom. I still need to find a copy of the mag. talked about.

Yes, Dave, that's it but mine doesn't have the threaded hole and plug. Thanks for the link Mark. The guy I got it from seemed to think the "M" was the one to get but he passed away and I can't ask him about it. If there is a difference it is slight and I can't imagine it would make a noticeable difference. Anyway, thanks for the responses!
