Stock rod bolts will fail and cause alot of damage. Maybe even a piston failure. you might wanna keep it down around 5000 till the bottom end gets built. Get the stock crank polished and prepped, install arp 2000 rod bolt and a good mini dome piston and then your limit will be the cam and valve train..On 2006-06-20 13:40, psivory wrote:
I was just curious as mine has never seen over 4500. I am running stock bottom 289 with Windsor Jr. heads, scorpion roller rocker arms, hardened pushrods with guide plates, and a DUI Ignition system. I can't see that I would ever go to 6500 rpms but was just wondering what the approximate limit would be.
