Longevity of High Output Motors

[Massive Type IV]

Last night the 3.0 turned 9000 miles since it's birth in March 05.....

I cahnged the oil when it came off the dyno, but not since it was installed in the car.... (trying to promote wear)

It hasn't used but a tad over 1 quart of oil over the 9K span its been in the car... I average 75 MPH on the highway at 25-27 MPG...... Engine produces 196HP to the rear wheels and 235@ the flywheel at only 5500 RPM....

The longevity of a correctly configured and assembled engine isn't a damn bit less than a stocker -- Do something wrong, mess up the combo or run it lean and things drastically change.
