I built two Ford motors last summer. One threw a rod thanks to the oil pump. The other is down thanks to Lunati, but not out. It'll get a new cam and get back up and running. The 460 is a pretty bad A$$ motor. Huge bore and short stroke. It's got one of the best bore to stroke ratio's of all motors ever made.
Anyway, had four 4 quads when we lived in AZ. We could open our back fence and hit up 3 million acres of desert without have to trailer them. 2 hours drive east were the sand dunes at <a href="http://www.riderplanet-usa.com/atv/trails/info/arizona_10347/ride_8ea1.htm">Hot Wells </a> and 5 hours west were the <a href="http://www.blm.gov/ca/st/en/fo/elcentro/recreation/ohvs/isdra.html"> Imperial sand dunes </a>at Glamis, CA. Both were great for camping and after riding those places, no where else comes close. Montessa Park in Albuquerque has some really good climbing hills and a great MX track.
I've had my quads upside down at all those places...
