Yea, its off a Boss Hoss Motorcycle which they put Small block chevy and Bigblock (502) chevy engines in.
So I'm pretty sure if it can pass water quickly and effianctly (sp) for that itll do it for the 3.0.


Anyways, figured out the problem.. Finally.

When the cooling fans would kick on it would short out the waterpump and cause it to quit running, so after the fans kicked on the coolant stopped and it just kept on rasing.

Thanks anyways!
