I believe you will struggle to get a 100 crank in and working.
Built a few 2.1's @ TSR and to use the diesel crank needed loads of work to the block to get clearance.
Also that long a stroke means you will be limited on revs.
95.5mm will go in an ABF...it hits the oil squirters, so you need to 'clearance' them...and as long as it's fully knife edged, lightened and balalnced, it's good for 8000-8500 RPM all day...
But it brings its own problems.
Trigger wheel?
Rods? Can't use ABF.
Pistons? Can't use ABF if you are going 2.1.
Compression?
What compression?
10.5:1 is useless on big cams...
It can be done...most of the bits are in my garage ready to go...but you need to know how.
100mm stroke must be difficult...and I'm still unsure how you get to 2.3?
