The 96 only had a 4.0 stroke. where as the 103 and the 110 have 4.4 inch stroke. I guess my question is since they started using an assembly with a 4.4 inch stroke in say the 2009 110 inch cvo's did they just decide to go ahead and use the same 110 assembly in the 103 ?

I guess what I trying to get at is someone told me they are putting 103 assemblies in the 110's, ( not strong enough to withstand a 110 motor). Where as if the first 110's came with this assembly, they are really putting 110 cranks in the 103's.

Same crank only difference in engines is bore size. Problem with all later twin cam engine was a weak crank when they went to the floating bearings instead of the double timken's. Pressed crankpin design has always been a weak point with larger bore motors and the high ratio comp/ clutch basket setup, why so many of them scissored so easy.
