SD421 intake manifold
Someone had told me that someone had reproduced the SD421 2x4(bathtub) intake manifold. Is this true or just a figment of my imagination. And this is only the second time I have had a chance to post a question. Just curious. Thanks.

If I do them they will be for 65 and newer heads.I think the interest I have had so far would put them in the $3000 range.I wont do them at that price.Tom

Great news. I assume it's a 1965+ flange?

The one I got has been machined for 61-64 heads BUT it looks like it was cast with the bolt boss for late heads also.Will know more when I get it in my hands.Tom

Well that's potentially a great idea. I didn't realize any were cast with provisions for both head bolt patterns. Very smart if in fact made that way.
