Hi Clive. I originally got the photo from you without the numbers on it in my “Engine Never Started” thread. See below from August 2. I don’t know where I got the version with the numbers on it. But it came during that conversation. At any rate, I used the pic with the numbers on it to believe I had a 4.2 flywheel.

Scot,
The 3.8 E-Type flywheel is scooped right out on the front side and is much lighter than the 4.2 version. The extra machining will be seen if the inspection cover is removed from the front of the bell housing.
The engine number will also be stamped on the periphery of the flywheel and can probably be seen though the timing hole in the top of the bell housing.
Here’s a 3.8 E-Type flywheel on the right beside a regular 3.8 item

That is, I thought I was safe until I found in talking to Steve in this thread that there was more to the story. Fortunately it all turned out well and I have a set of matching components to get a new geared starter that is compatible with the 4.2 engine.
