stock bottom, what's it good for as far as power? i've been told rod bolts go at about 500crank so i'm a little worried as to how far to go with it. honestly i just don't want to have to pull the motor and do rods pistons and crank

 

i'm at nearly 450rwhp stock bottom... it's doing just fine...

 

well i mean i'm turbo and i'm making around 460whp but i'm not sure how far i can go with this. i'm thinking valve springs and retainers and then 10lbs

 

i dunno... i've heard 550-600 is safe for a stock bottom end... longevity is a different story. But personally I'm a big believer that if you do your regular fluid changes when your supposed to and you don't absolutely dog the crap out of it, you should be fine. That is, as long as your tune and supporting mods are installed and calibrated correctly...
