I even have casting numbers to look for. (unfortunately my shortblock is at my father's shop and I don't have instant access to it to check what I have...)

based on the casting numbers on my block, it was on the earliest lq9's built. I'm guessing late 01 or so.

Yea, it's no secret that the 9's got the beefier rods and teflon coated piston skirts, it's just a question of did the LQ9's have that equipment since day 1, or were the very early production LQ9's equipped with the weaker rods

To aid in this the 9 rods you got from me J were def a 02 or 03 set, not 04.. But to say the least they have been a bigger rod.. Bottom line here is that the bottom end will hold 700HP no problem if you have you **** in line.

PERIOD
