i had read that the 2nd generation connecting rods are forged steel versus the 3rd generation connecting rods which are powdered metal cracked cap rod, does anyone know if this is true and can we use the 2nd gen rods in the 3rd gen motors? thanks

 

The 2nd gens will work fine. The 3rd's are not powdered metal. Rather a C70 micro alloy steel forging that has properties which allow them to be be cracked.

Unless you are going way crazy in HP, the cracked cap rods are very good indeed.

 

thanks Don, you are the man, having the proper info always helps

 

Define the limits of crazy HP?? lol

 

Crazy HP = ponies that can't fit in your wallet!

 

^^^^^^^^ so true! LOL

 

I guess 1289hp isn't crazy enough!

 

Cuningham rods from what I hear are pretty sweet. Anyone running those?

 

I have been running cracked Caps in mine over 100lbs of boost for 16 mos. My new motor has Cunninghams in it though whenever I finish it. Tim

 

I think rob(O.T) is running them in his

 

yep, Cunningham rods here! Although many have done just fine with Cummins rods I chose to add some strength when I had my engine built/

 

Clarification........ 3rd Gen rods are strong? but 2nd Gens are stronger for some reason?
