Maybe the 4.8's are weaker? I'm used to reading about the LQ4, which people push to 700-800 on the stock bottom end relatively commonly.

Yea I've read the gen 3 in its stock form is good for 600 then you start bending rods. Gen 4 things got a little beefier

theres a dude in the drag racing section running 9's in a 4400 lb truck with a 4.8.

Year for year, the 4.8 should be the strongest shortblock available if stock. Most cylinder thickness and less stroke.

Are these the 60lb direct fit to my 2004 stock 4.8 rails?
