| | | | Joined: Jun 2005 Posts: 481 'Bolter | | 'Bolter Joined: Jun 2005 Posts: 481 | I would like to know where to attach the bracket for the crankcase draft tube. As some of you may know, I have been working on my restoration project for some time and the truck has been disassembled for many years. I should have done a better job of taking pictures. I would like for someone to post a picture of the draft tube bracket on their truck engine so I can see the proper location and method of attachment.
Thanks in advance.

Here is a 1954 235 engine' road draft tube. You can almost see the metal "strap" around the tube and where it is attached to the block with a small bolt. The earlier 235/216 engines' road draft tube was, I think, attached differently. I think the shape of the road draft tube changed when the front motor mounts changed (late 1950s?). Pre '68 Dave would be a source of knowledge of the different road draft tubes, and where they attached to the block? | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | ....don't have a pic either but depending on the model year some did bolt to the bottom of the pan of which I'm fairly sure.
If you do not want to use a draft tube Deve has a nice article on his site how to use a PVC vale made from freeze plug/grommet and PVC valve. I did it on my 261 engine. Just an idea..... | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Depending on year of block and tube used the mounting position changed. In Tim's link you can see one of the mounting positions. Most blocks also have another mounting option about half way between the distributor and dip stick, just above the pan rail. In this LINK you can see where it is (there is a bolt in the hole).

All of your responses helped to confirm my thoughts as to the location of the clamp. I frequently visit Deve's website, especially while getting the motor reassembled. There will be many more questions as I continue with my frame-off project. I am always appreciative of the Stovebolt's vast experience. | | |
