I'm trying to identify some connecting rods in an engine I purchased a while ago. I called a few rod manufacturers, but none were able to help. Here's what I know:
H-beam
5.7"
99% sure they're forged
ARP 8740 cap screws
No identifying marks aside from stamped 3 to 4 digit number (different on each rod)
Just your typical generic imported H Beam rod. Probably CAT, RPM or Pro Comp Elect depending on when it was built. It's not an Eagle, Scat, K1 or Molnar. The shoulder profile is totally wrong.

I though you posted in other thread this stuff was SCAT? SCAT does use those particular bolts in some of their H beam rods.
The crank is SCAT, and I assumed the rods were too until I looked into it.

Alright, still haven't been able to track down who made the rods, but I called ARP and they gave me a generic spec of 75 lb-ft. for a 7/16" thread diameter 8740 bolt using their special moly lube. I guess with nothing better to go on I'll use that.
