High mileage engine, replace rod bearings before knock?
Hey guys, I have a chevy 350 crate that has been abused terribly. I just had the heads rebuilt and am replacing the cam, lifters, timing chain, springs, oil pump and all new gaskets. Since ive got all that taken care of, should i replace the rod bearings now, or wait till the motor starts to knock? In a few days or possibly tomorrow, I am going to be raising the engine to get the oil pan out and I was wondering if it should be done since i am going ahead and getting the oil pan off... Ive already spent WAY more than i expected and i figured spending another 20 dollars on new rod bearings wouldnt be much of a gamble... but im curious to know if its safe to replace them on a high mileage engine... the cam i got is brand new so it will have to be broken in at 2000 rmp for 20 mins. Let me know what you guys think i should do!! I really dont want to have to sink more money into this engine anymore because i am BROKE! help me out guys, THANKS!
