I just wanted to share with people who like this stuff. I finished my one ton axles and ZZ4 crate motor installation and spent the last month or so wrapping up the loose ends and breaking in the motor. Today, I changed the oil and went to nearby pit with some long steep loose gravel climbs and rapped the motor up (like a moron) to 5500 and climbed the hills a bunch of times. It was pretty fun but I think all the suburbanites walking their dogs down in the pit did not like the noise . . . because they left.
