I've been looking for this for a couple of years now. I even bought one in the states and had it shipped over but it was an earlier head and was too small. It's in a pre war racing car and I think it's around 1930. The head in the car is hopelessly cracked. The face measures 75 x 17.5 cm. There are two numbers cast onto the head. They are 215 582 and S-3. Anybody out there got a collection of Buick parts or can put me on touch with someone who has? Here's hoping. Ed
I don't know but I have heard that the early GMC 220-270 engine was a derivative of the Buick 6. Maybe or maybe not. But you might look into this.
As always, Rich is right, but the lineage and interchangeability is not clear: 1931 - GMC took over production of Buick 6-cylinder engines. 1933 - GMC designed and built 6-cylinder valve-in-head engines in 8 sizes, from 221 to 707 cid. 1934-1937 - Oldsmobile 6-cylinder L-head engines were used in GMC light and some medium duty trucks. 1936 - Major changes appeared in all GMC conventional cab models. 15 new models were released, including 1/2-ton pickup and panel trucks with Olds engines. All other models had GMC engines that were in nine sizes from 239 to 707 cid. So, yes, no, maybe. jack vines
These guys will have the answer if anyone will. The antique Buick experts. http://forums.aaca.org/f165/
Buick Club of America, Hemmings Motor News for a start.In the Later St-.8 different series cars used entirely different engines. In 1931 they used three different engines. Probably the same with the sixes
Try posing your question over at the www.inliners.org website. There are a lot of knowledgeable folks that may be able to help. Also some parts hoarders too.
