Default 6.2 crank setup. 4.000” crank with 6.125 rods stock block?

L92 6.2 build. Need some help figuring out a crank.
gonna be a 24x reluctor wheel crank.
gpi ss3 camshaft
diamond forged pistons -2cc 4.065 bore
btr forged rods 6.125
Can i fit in a 4.000” forged crankshaft over the 3.622 without machine work besides balancing the rotating assembly? Plans on a small 150 shot nitrous every once in a while. Block is currently bare.
Power levels? Issues?
also recommend me performance capable main bearings, rod bearings and cam bearings.

Are the pistons for a 4" stroke crank?
All you will need is for it to be balanced and that's all.. Haven't had to clearance one but never hurts to double check everything during installation.
I use King bearings in all the LS engines from daily drivers to race cars.

Main bearings King MB5013XP (For aftermarket crankshaft)
Rod Bearings CR807XPN
Cam Bearings Durabond CH25

unfortunately they are 3.622 stroke pistons. Changed my plans after the fact of having bought them. Luckily they’re new in box and i can exchange them for a 4” set
