DOES ANYONE KNOW IF THE STOCK LS1 RODS ARE MADE USING THE SAME PROCESS AS THE NEW POWDER FORGED RODS FROM HOWARDS RACING CAMS?

IF SO, HOW MUCH HORSPOWER CAN THE STOCK RODS HANDLE WITH FORGED PISTONS?

I KNOW THEY ARE CONSIDERED PM RODS AND SO ARE THE LT1 RODS, BUT ARE THEY MADE THE SAME WAY/MATERIAL?

THANKS

GKN makes rods for GM as well. I saw something regarding the LS rods made by GKN, but I cant remember where. I'm using stock LS1 rods for my build, with upgraded bolts

It would be interesting to know a little more about the production of the factory rods.

specifically, are the rods are powder forged? what grade metal are they made of?

 

can stock rods handle @ 700-800 horse with nos(300 shot max)?

 

i wanna do something like that with my truck too, i wanna get the H-beam 6.100" eagle rods they are around 280 bucks plus S&H. what kind of pistons are you gonna get?

 

Im not taking a chance with the stock rods. My 98 z28 cam just threw a rod in the side of my block. It was the first thing to break on my car.

 

diablo - i was gonna use stock rods and get diamond pistons, qc is top notch.
zeeya - what rpm and rwhp?

 

heres my dyno chart. http://carolinass.com/377hp.jpg

I just upgraded to the TSp 231/237, th 350, 4200 stall and a 9 inch when she blew. I had it cutom tuned. I never hit the rev limiter. And its set before 7k.

 

YES, these are powder forged. Howards has many styles for many app's. I have heard OEM units are limited round 500hp before they fail, but there are a zillion variables to consider on the way they are used. Racing classes that mandate all stock components have had very good success with OEM pieces.
