SHO-Z Posted October 3, 2008 Share Posted October 3, 2008 I keep hearing about the L6 engine in the Z. Here are some brain teasers on types of head designs. This book was published in 1918. See how many you can figure out. They are all alphabet letters. Now here is one showing that maybe some of the new designs are not so new. Hemi dome roller cam dual ignition. The last one is the real brain teaser, what type of engine and who made it? Quote Link to comment Share on other sites More sharing options...

blue72 Posted October 3, 2008 Share Posted October 3, 2008 Shall I start the guessing? The first one is unmistakably a T head. Next to it, on the right, is an L head design. Bottom left would be an I head (the height of it), while bottom right is an F head engine. Crazy some of what they were able to get away with back then. Straight six engines with three main bearings, super low compression ratios, pour in main bearings, and extremely low rpm limits to name a few.

cygnusx1 Posted October 3, 2008 Share Posted October 3, 2008 I know Alfa Romeo used the Hemi head design as early as c1915. Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted October 5, 2008 Author Share Posted October 5, 2008 Well I we have a winner "Blue72" on the first sheet. And the Z engine should be an "I"6 by the old way of calling out engine types. I will wait a couple of more days on the other 2 engines. Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted October 8, 2008 Author Share Posted October 8, 2008 No Guesses so here is the rest of the story. The sleeve valve engine is a Willys Knight and was a V12. The overhead cam engine is a Miller race car engine built by Wisconsin. The only engines I have ever seen that were made by Wisconsin where big old single cylinder engines for generators and such. And they were not fun to start with and old rope starter! Quote Link to comment Share on other sites More sharing options...
