you can get wiseco pistons and shot peened rods and do 500whp

hell a guy did 750 whp in vegas a few years back on stock bottom end but it blew up on the trip home

me myself i wouldn't go over 450 whp with stock internals

and for the love of god use ARP rod cap bolts cause thats the weak link

the stroke of the motor and revving high will stretch out the stock rod bolts and BYE BYE RODS!!!!
