Merle Coggins Posted August 23, 2017 Report Share Posted August 23, 2017 It doesn't look like a Mopar flathead to me. Maybe a Ford or International I6 engine? 1 Quote Link to comment Share on other sites More sharing options...
Cebreros Posted August 23, 2017 Report Share Posted August 23, 2017 Yup, I have no idea on the answer to this post but just wanted to throw in that some Hudson flatheads had that casting stripe running along the center and sides of the head but this is not a Hudson.

greg g Posted August 23, 2017 Report Share Posted August 23, 2017 Those welsh plugs are pretty good indication it is not Mopar, can you post pics of the manifold side. I think all those flat head six designers were all cousins if not brothers, they look very much alike. Quote Link to comment Share on other sites More sharing options...

greg g Posted August 24, 2017 Report Share Posted August 24, 2017 How long is the head? 28 inches rules out mopar. Quote Link to comment Share on other sites More sharing options...
greg g Posted August 25, 2017 Report Share Posted August 25, 2017 Looking like Hudson fits the bill. Quote Link to comment Share on other sites More sharing options...
dpollo Posted August 25, 2017 Report Share Posted August 25, 2017 The Hudson looks close except for the number of "frost" plugs and the heater pipe on the cylinder head. My money (canadian dollars) is on Pontiac Quote Link to comment Share on other sites More sharing options...
