over $300? that's gonna be a no from me dawg.
if you're willing to drop the coin, get a flow kooler.
the $99.95 milodon doesn't move the needle for me when a stock AC/HD cooling pump is probably the same or better and the flow kooler is only like 30 bones more.
remember that it's a cooling system. all the parts have to work together, and this starts with the correct pulleys for the application.
and don't cheap on a t-stat. get a good quality hi flow unit.
