I havent seen any input shafts break, but these trannys are getting to be 45 years old, so anything can happen.

Yes; the belt-driven centrifugally-supercharged slant six in Steve Nitto's Duster twisted a 904 input shaft in two at Vegas, earlier in the year...

If it happens with a slant six, I can only guess what its lifespan might be with a small block stroker motor...

Just my 2-cents...
