I will add ive one motor ive never checked stretch, apart each winter with the entry level eagle arp bolts. #63 and never look back.

I really dont know how I got stuck on the stretch thing, sorta like the op, years ago I just wanted to do "better" and that goes back to why I wrote that many think at our power levels we can be semi close and never have a rod bolt issue.

But if the torque value was the best way, why do so many use the stretch?
