I'm sure this thread has been done before. . . but the search feature is too friendly about 3 letter words, "rev" being the key word here. . . and I am having a hard time finding posts on the topic as a result.

Anyways, I'm running a built top and bottom end. The head is ported.

How high are you guys with similar setups reving?

I would like to eeek my power band out to 9k if possible - looking forward to some feedback.

Thanks guys

built/balanced bottom end + valvetrain that can handle 9k rpms and your fine..

Just make sure you port the **** out of the head and get some wicked cams cause LS doesn't like the high revs as-is

You'll need some big cams to make power to 9K.

big cams will get you to 9k

tuning is key as well

My primary concern isn't going to be making power up there (I'm fairly confident in the port job I got and that the crower 402t's will help me make power that high)

My main concern however was the rocker arm assembly of the LS head. . .

I am wondering if the LS rocker arm assembly is stable at 9k? Anyone have any bad experiences with this?
