Ah Ok, yeah that seems to be one of the better methods if you are not measuring stretch. I know a guy tightened his to BMW factory settings and it let go and put a rod through the block. But there could have been other things at play aswell. My friend just used stock bolts for his S54 as he didnt see ARP available in that size, hes just gonna change them regularly. I think i might invest in the ARP tool and do it that way. Have you used NG much for engine builds?
