Scat buy their fasteners from ARP.
This is what it says in my ARP catalog about how to tighten their rod bolts, p.14:
'The....proper preload can be attained in a con rod by applying proper tq using a tq wrennch or by measuring the amount of stretch in the bolt using a stretch gauge.....The tq method is sometimes inaccurate because of the uncertainty of the coefficient in friction between the bolt & the rod. This inaccuracy can be minimized by using lubricant supplied by ARP'.
I read from that that ARP believes the stretch method is more accurate.
