I am dropping my motor off Monday and i have to decide whether or not the stock cam bearings will be fine. I have a brand new fresh GM shortblock that was never run . Will the stock ones be fine? On juice it is going to be putting out 650 hp or so. It's only a couple hundred $ extra i think to do it so I was wondering. Thanks

 

I don't think it will be much, go with some dura bond coated just so you know they are new

 

It should be under $100 to install new cam bearings, depening on how aggressive the cam is I'd probably change them out to the coated ones, just for the peace of mind.
