Anybody have an idea on who makes a big bore kit for a 1999 600 big block motor. I can't seem to find any, they are all for the 600 with exhaust valves.

thanks

Bolt on a set of exhaust valve 700 cylinders, along with the eletrical and exhaust.

I have done a couple of 600 into 700 upgrades. a set of 700 cylinders w/ pistons and rings and head will bolt right up.. no need for the exhaust or elect. I went back the the 600 goes just as well as the 700...

We buid a wicked strong 600 into a 800 and is trailable to boot.
