Wisconsin T-Head Engine

Post by Jimbo » Mon May 04, 2020 11:59 am

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?

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.

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.

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!
