I have a brand new 4-bolt shortblock here with ARP rod bolts pressed in and fully balanced. I was wondering if anyone thinks the motor will hold up for a long period of time (30k+ miles) with the Ai 200cc package, full boltons etc (about 480-500 crank hp). Max RPM will be 6200 or so, not much higher than that.

I read a few threads where some people think they will handle 500 no problem, but i mean over the long haul do you think they will?
