countrytravler Posted October 28, 2014 Share Posted October 28, 2014 Looks like 1932 to 1947- What have you used that works?ThanksDave Link to comment Share on other sites More sharing options...
vintchry Posted November 1, 2014 Share Posted November 1, 2014 Dave, Gaskets are the same, but 37-48 heads work. In 39 they started to put reinforcing strips along the bolt areas that run the length of the head. Rob Link to comment Share on other sites More sharing options...
countrytravler Posted November 2, 2014 Author Share Posted November 2, 2014 According to my Hollander book, the head from 31 to 48 will interchange. Also includes some of the Dodge flat 8. The cutoff in the book was 48. Have a customer putting a 47 in a 40. So far the flywheel to crank mounting is different. The fluid drive is different. Let you know the results later.
