6200?

 

I have no idea of what it could be but i am gonna put a L98 in my car soon so i will subscribe

 

May live for awhile after 6200 but to be more onthe conservative side, i will say shift by 6200, aim for peak by 6. I want to say LT1's had stronger bottom ends and thus some of those guys go to well over 6500, but hard to say.

 

I'm glad you phrased the question "stock shortblock". The TPI intake system is producing almost no usable horsepower above 6K so winding it higher instead of shifting it back into its power band is pointless.
Other factors exist that affect the engine's ability to live at higher RPMs. How many miles on it, how well it was maintained, how good the factory balance was.
The factory balance is kinda like picking a number from 1-10, (how well it was balanced), with 1 being the closest balance and 10 the outer limit of the tolerance. Most are in the middle with fewer as you go towards 1 and 10. There are still some 1s and 2s as well as 9s and 10s. Naturally a 2 will tolerate high rpms much better than a 9 so you can't say "any L98 will run just fine at 6500". A "1" would live just fine spun to 7K and a "10" would not live long past 6500.
An L98 with 200K miles and a lot of wear would tolerate high rpm much worse than a well maintained one that has only 50k miles on it.
Lower end bearing wear due to poor maintenance (being run over on an oil change) is as an even bigger factor. Even the smallest excessive clearance in a rod bearing introduces an impact load on the rod when the piston changes direction. So a well balanced engine with only 50k miles on it that had been run 12,000 miles on an oil change would face certain death above 6200 rpm.
So the correct answer is: "it depends on...".
how good the factory balance was,
how well it has been maintained,
how many miles on it.
(now, whoever said I couldn't complicate a simple question?)

 

Stock L98? By the time you get to 6200-RPM, the race will be long over....

Edit: If your asking about the shortblock alone, well it depends, of course....

 

Im just asking because I "might" have flashed my old L98 to 6500 the other day haha. I know with a rebuild and better rod bolts the stock parts can handle that; I really just was looking for a reassuring pat on the back to say "No son, you didnt just wrap the hell out of your motor. It will be fine"

 

I took mine to 6000 RPM all last summer. No problems...yet.

Well the thing is a lot of it has to do with time. Electric motors for example draw a much larger current then their actually rated for on the start up but its ok because the duration is short. Even if you ran your motor up to 7k for 10 seconds most likely it wont fail (unless it drops a valve or something). You may have shaved 20k miles off its life by doing that but thats where the the time factor comes into play. If you accidentially reved it to 6,500 for a tenth of a second I wouldnt be to concerned. The factory rated these motors to 5.5k and thats what i would assume the rev limit would be for the average factory small block chevy.

 

If you cam/heads the car I wouldnt want to take it much over 6200 rpm if your making any decent hp. This means cam/heads/intake package that will peak hp at 6000 or so rpm. 6000-6200 is about all the higher i'd go on stock rod bolts.
