What do you guys think would be a safe redline for stock lifters with 92k on them?

I am putting in a 224/230 cam with new valve train other than lifters and it makes power up to 6100, so I was wondering what a safe RPM was to set it at when I get the reprogram.

Thanks guys

 

92k lifters and raising the limiter...

 

stock lifters are rated at 6500 rpms

at 77k i ran 6300 rpms for 18k before changing my engine set up.


They should be fine at 6200.

 

I'll say this, reusing stock lifters are like opti's... You'll never know when they go. Some setups they may last and some simply don't. Definitely take a good look at them before reinstalling them.

 

Yea I definitely plan on it, but im not gonna replace them with the 850-16's and the 875-16's are outta stock anyway...but i will see what they look like, everything i have pulled so far has actually been in good shape

Thanks guys

 

I would worry more about the stock valve springs if your still using them. The stock lifters will be fine to 6100 to 6500 RPM as long as you don't run in that range for an extended periods and have the lifters pump up on you.

 

Like I said in the previous post, I am replacing ALL of the valvetrain other than the lifters....
