Okay, so the bottom ends of these undersquare motors can rev up to 7k or so.  Let's
discuss the valvetrain a bit.  That 500hp streetable motor build by Dialynx used solid lifters.
Is that something that is necessary to rev high?  I know on the 20v_Kruemmer list one of the
things that is discussed and done is to go with solid lifters.  Is that necessary to get a redline
that is around where it is stock?  The article says the motor "revs happily past 7500".  Yikes.

Here's that link again:

I didn't notice it was one of two 500hp 20vt articles.

I think the first of those two is the one I'd prefer.
