Paul and Kevin,
I am a little confused ( as usual)
The Photo showing the flexplate also shows the rear housing - which is
different to the 13B as it has an extra bellhousing mounting hole at 11
o'clock - is this normal for 20B housings ?

Yes it is. It does have an extra bolt.

Paul,
If anyone out there could give me a position of degrees on that extra bolt
hole of the 20B. I could have that included in the bellhousing pattern.

It could be that may 20B's are made-up of 13B parts and don't have that
extra bolt hole so some builders won't need it. However I have already
discussed with Butch about an extra bolt hole at the top of the engine to
replace the 8 o'clock position bolt hole when a LH ( facing the prop)
starter position is used. Butch feels it a good idea and agrees it could be
incorporated into an aluminium end housing.

Any number of extra bolt holes could be used as the bolt pattern are all on
the one diameter except one. So it would be easy to include the 20 B bolt
position as well as our extra one as the facility for these are already
there on the top flange.
