I too have a 6000 rpm engine, I love outrunning folks turning 7000+ and
listening to them complain about the number of failures and amount of
manintenance required to keep it up there.
I did however go to the Carillo rods a number of years ago due to the
number of stock rods butchered by our local machine shop during
reconditioning. I decided to hold the rpm down both for authenticity
and engine life. And hey, if you keep the tall 3.7 gears in it, you've
got vitually no use for that 7000 rpm anyway.
