I have an 01 Duramax and I will be putting in Carrillo rods, Cam, Arson stage 2 CP3, cutting and coating the stock pistons, Keying the Crank, Cam. I will also be putting dowel pin on the water and oil pump gears, Flow benching heads after porting, balancing rotating assy W/ super damper and socal flexplate. Profab manifolds will be put on with new turbo S480 single injectors 50%. This will be and everyday driver race and pulling truck but the one thing i wasent sure to go with was if i should get hardened Bearings of stock ones?

Im doing 'H' series bearings on the mains and standard bearings on the rods. JMO.

Why skimp?
Not sure he was trying to. Just asking which was better. Hardened automatically means better?

Does the duramax have issues with main cap flex or bearing walk? Personally I would save the money on main studs and spend it on something that made me actually go fast. Unless there is a documented problem.

What made you decide on this? I would have guessed hardened on the rods and standard on the mains. Especially since rod bearings tend to take a pounding on serious engines. Any reason you chose this particular combo?

Even though the cranks for these engines are nitrated they are very soft, in fact if you take a file you can dig right into the crank as if it were butter.
My only concern would be if hardened bearings would beat the crap out of the crank verses the way standard bearings would treat the crank. Main and head studs will be done alone with honing cylinders for a little more clearance, decking the block, surfacing the heads, and de-liping the pistons.
Thanks for any sugestions
