hey guys, ive got a crate 350 that has been abused by the previous owners... i got the heads rebuilt with new springs to match the mild cam i got. i am going to be raising the engine to get the oil pan out and was wondering if i should go ahead and replace the rod bearings before it starts to knock... i dont know how much wear there is on the rod bearings, but i planned on checking the wear as soon as i get the oil pan off... let me know what you guys think i should do, the cam is brand new so ill have to break it in at 2000 rpm for 20 mins... is that safe for new rod bearings? Thanks guys
