Stock bottom without even rod bolts? 400? ------------------

depends on how long you want it to last. my first 302 i rebuilt had nothing but stock internals not even arp rod bolts. i turned it to 6000 rpm all the time and i never broke nothing. hipo 289s were built from the factory to turn 6000 rpms time and time again but they also had strong bottem end components compared to a regular 289. i wouldnt hesitate to put the power to a 302 but at the very least have arp rod bolts pressed. one of the 302s weekest points is their factory rod bolts. arps are 5 times stronger.------------------

I've buzzed stock cast crank bottom ends 8500 rpm's... I've never seen a 3" stroke 302 break a crank... Couple guys up here in Seattle are pushing 650 + and dipping in the mid 9's with stock cranks,rods with arp bolts....pretty stout if they're built right!!!------------------

Yeah, I would say 400 in a street car. But in racing congitions (circle track) whare you know you're going to be beating on it, stuff minght break. ARP "Wave Locks" and well balanced parts, you should be fine.
