Hi Paul,

Do you know what size bolts are used to mount a 13b on an engine stand?

My core didn't come with a bellhousing. Thanks.

Bob

The bell housing bolts are 8 mm.  Probably 1.25 mm pitch. Don't' hold
me to that last number as I have none here in the office to check.
Tracy knows more about that then me as he ships them with
his redrive I think.

The bell housing bolts are 10mm with a 1.25mm thread pitch  but I'd
recommend not using them for the mount to the stand.  That's where the
redrive will go if you intend to use one.   Mounting the engine on a plate
with the oil pan bolts and the three large motor mount bolts on the bottom
of the engine is about as simple as you can get. Sandwich the plate between
the oil pan and the engine.  That's how my test stand is built. (as well as
the mount in my plane).

Opps. I guess I forgot the threads when I measured the end housing.
Brain fade. Thanks Tracy.
