ARP main bolts oil pump clearance

Why should ARP care when they have a monopoly on fasteners?
When Procomp (Speedmaster) finally ruin all the medium priced parts manufactures out there and all that is left is their hokey stolen part designs or high end manufactured parts like jesel etc, that's when the fun and games is really going to start...Having one fastener that won't fit will be a dream compared to what they will be sending you :) They will have the monopoly...
