Wisconsin T-Head Engine

[Jimbo]

I have a Wisconsin T-Head engine. It is Model B 4 1/4" by 5 1/2" bore and stroke. I originally planned to make a Speedster type race car out of it but now I am not so sure I ever will. I am wondering what make of car (or cars) this might be original to. It looks a lot like the engines used in some early Mercer speedsters. Does anybody have an opinion about value?

Need pictures, both sides, some detail. Thanks

Don, This engine was complete and running in a big Buick a few years ago. Later the Buick got its own engine back and I bought this engine. I have just the engine. No magneto, no carburetor, no distributor. It is set up for 3 spark plugs per cylinder. I was planning on building an early race car but I have given up on that idea at this point. I have adapted an early (ca 1912) Cadillac flywheel to the crankshaft flange. No ring gear, no starter. If someone can show me how to insert a picture into this reply, I would attach a picture of the engine. Jimbo

The Wisconsin Model B was used by quite a few cars and trucks - Stutz, FWD to name two.
I have a big brother to the "B" which is the model PT which is six cylinder (5-3/4" x 7")

Heck of an engine! Do you still have the original flywheel?

Below is a photo of my Wisconsin PT

If you missing the valve covers I have a pattern and core box to cast a set.

How do you post pictures on this forum?

At the bottom of the page you are posting on while replying, there is an “attachments” tab. Click on that and then click on “add files”. You can then pick the photos you want to post from your computer or phone. You then choose “place inline” and it will be inserted into your post.

Here is a pic of Jimbo’s engine he sent me earlier.

Yup Wisconsin. I believe (if they followed the same practice they used for the six cylinder engines) a serial number should be stamped into the top of the crankcase between the cylinder blocks (key word "should")

Looks like it had an oil tank.

Can you post a photo of the front gear case cover?

This engine doesn't appear to use valve stem covers.

[Tharper]

Perfect! The reason I wanted to see the timing gear cover is that the marine
version is identical with the exception that the timing gear cover has a flange
to facilitate attaching a marine style reversing gear.

Nice engine, wonderful condition! I hope it finds a new home!

The Model B's are often used in trucks. FWD in particular used them for the WW1 military contract trucks, plus civilian models as well. No doubt other company's used them as well.
Cars; Stutz for example used the Model A . The Main difference is the crankcase casting. The Model A has wide mounting arms that bolt directly to
the main rails of the cars frame. The Model B mountings are quite a bit narrower as it is intended to bolt into a vehicle with a " sub-frame " to mount the engine and transmission separately from the main frame.
