that way the nut will give instead of stripping out the block threads,same on mains

if the motor is balanced it should be fine,i mean think about it, the crank spins on oil,and the oil isnt enough to make it like a hydrolic force ,that keeps it centered ,so the crank doesnt eat the main bearings up,so the balancing is critical,or those lil crappy bearings are gone
i wanted to have a set of special precision bearings made for rods,and mains,like motorcycles,
but make them 2 piece ,with a oil channel in the middle so the oil will flow to all gallies,man you could spin it to 50000 prolly with out a worry 8)

If you blow a head clean off the block( or damn near) or the crankshaft out the bottom.... you got way worse problems than some stripped bolts... :P jk
You get a better clamping load with studs, among other advantages
This is a copy paste from the link posted
For performance applications where a choice is available, studs should be used whenever possible instead of main cap bolts. Studs provide the ability to obtain much more accurate torque values because they don't twist during tightening as bolts do. Because studs remain stationary during nut tightening, they stretch in one axis alone, providing much more even and accurate clamping forces. Also, because the use of studs results in less force applied to the blocks threads, this extends the life of the threaded holes in the block. This is especially important with alloy blocks. The use of studs also eases main cap installation, and contributes to main cap alignment. There is less chance of main cap walking because the studs remain stationary during cap clamping.
