ALL of the intakes listed by myself and Barry Weeks are still around. You have to look hard and get lucky. None of them are still in production except the Offenhauser.
Just as a point of interest, the shape of the Sharp, Edelbrock, Weiand, Edmunds and Tattersfield were kind of "U" shaped and because of that they cleared the shifting arms on trucks with column shifters. These are the ones you need to look for, unless you are running a four speed or a T-5 five speed transmission. You also probably want a 2 x 1 intake as a 3 x 1 could cause clearence problems. Some of the makers of these old intakes did offer a 3 x 1 version, like Nicson.
The Edmunds was the only intake set up for water heating the intake. It might be the best choice and I have seen them at swap meets here in Texas and Oklahoma.
I've got some pictures of about four table tops of intakes for inline six engines I took at the Pate Swap Meet here in Fort Worth in 2004. The same guy was there in 2005. If you will email me, I can send the pictures to you. It'll blow you mind!!
