Re: What the max rpm to spin an ls1 My primary concern wouldn't be the bearings, but the stock rods/rod bolts... The rods themselves aren't terribly weak, but the stock bolts leave much to be desired. With upgraded rod bolts and a well balanced rotating assembly, I don't think you'd have any problems up to 7200rpm or so. I wouldn't want to turn stock pistons/rods much more than that, personally...
