how much power will stock rods survive?

I've got a set of Eagle sir's in my 416 stroker,just had the motor disassembled after a season of racing and the rods checked out fine,they should be fine for your engine also theres upwards of 500 h.p. in my stroker,i'm using nice light weight Diamond pistons,well worth the money spent..Of coarse there are guys that will tell you the Eagles are garbage,but there are quite a few running the I-beams with no problems me included,and for what it cost to redo a stock set,your better off with the Eagles......
