I was all excited about throwing a set of rods in a budget build and then the bigger crank had to ruin my dreams. Think anyone will make an adapter bearing?
It's sad that they just now but bigger rods in, kinda looks just like a Cummins rod. Maybe that's GM's supplier now :rofl:

I'm excited for this platform. Hopefully they have made some steps forward so those of us that are into more of the performance can hopefully push this one a little further with less stress of internals giving up
I really dont understand why everyone automatically associates the angled cap as "a cummins rod" trademark thing. Has no one ever seen the insides of other engines? You do realize thousands of other different types of engines use an angled cap?
6.0/6.4/6.7 Powerstrokes have angled caps.
The 5hp briggs and stratton on my lawn mower has an angled cap.
The angled cap is because the rod journal is so big now that it wouldnt physically fit through the cylinder bore (during assembling the engine)...so angling the caps is a geometric trick that manufacturers use to make it so you dont have to put the pistons in from the bottom... Its not so much "for strength" like everyone assumes.

But it IS a stronger design.I really dont understand why everyone automatically associates the angled cap as "a cummins rod" trademark thing. Has no one ever seen the insides of other engines? You do realize thousands of other different types of engines use an angled cap?

Your absolutely right though, tons of other engines use this design.

OK you master gearheads - let us not so informed, amateur gearheads know what you think of these changes in the new engine - are they good for reliability as well as performance, or not? In your opinion, of course. Fuel system, turbo, egr system, etc etc
That's the diesel oxidation catalyst - It's there to promote fast lighting and reduces emissions quicker than having it further downstream.

I'm a diesel tech by trade, you don't need to try and school me on rods.
It was a JOKE genius
Depending on what the base material is, this new process could yield rods that are stronger than forged 4340:thumb:
We will never know the metallurgy of these rods, obviously GM will not give away all their engineering/process devolopement secrets. Sadly, we will have to find the limits the old fashion way:angel:
