if i remeber correclty, mike mallory shot a stock race prepped rod out of his block around 550-600 horse,
i remember seeing nate, run 840 w/ 100 shot if i am right on a set of eagle rod's .
im not ot sure on the make up or other constuction of the rod's, bolts or pistons, but i choose to pick up a set of eagles when my goals surpassed 500, if i wanted a dd of more then 600 i would up for a better set then eagles though.
eagles can hold the power but very well still can fail sooner then a better product, but from what i read eagle may be using the same techniques to make their product now.
pretty much this is what i decided when i was looking for rod's.
stock=450 +/- 50hp
eagles=700 +/- 150hp
pauters +carrolos (sp)=1000k+
^^^that is more so to say which are better. but also tune depends on power out put and how much power they last for.
