The actual odd ball stroke MP cranks? YES! Very hard to find.
Aftermarket cranks? EZ-PZ. There out there available in ether main journal size and in 3.31, 3.58 or the 4.00 stroke. Bigger strokes are available. Hughes engines has one and at the moment, I forget who, also offers yet another stroke of 4.00+. There have been or still are 4.15, 4.17 & 4.25 small block stroke cranks.
