hp ratings

[Atl_Monte]

I've been told that the OEM('95) crank and rods in the LT1 are highly durable was wondering what are the ratings on them, and rould they be good in a non-nitrous blown engine or would it be worth it to look into some forged parts?

P.S.- before I get reamed out about askin so many questions, I have 3 95 LT1's one I got as a project engine out of a burnt up 95 T/A couple years ago, got to expensive to piece it together so I just saved it, then the one that I removed from my 95 T/A then the one I re-installed in my 95 T/A, not jsut wasting posts....

The factory rates the PM rods at 450HP. Two failures that I have seen documented occured at about the 600 flywheelHP level. The crank is probably reliable to a similar level. I would say the stock parts are reliable for most normally aspirated applications. But for a blower or nitrous, the small cost of upgrading the parts is cheap insurance. Start with forged pistons, and work your way toward the crank if money is limited.
