It's probably better than stock crank. On my Cag racing engines I use a full circle crank that takes up more space in the cases and makes more pressure in a smaller space. The GP3 cranks already look like a FC crank. The new crank has better bearings and is probably balanced better than a stock. The crank should not change anything, if it was a stroker crank you would need a spacer under the cylinder and or a different piston.
