May 4, 2007 update to the AMC Eagle project car

The price is right

This is what $0.00 buys you!
Not quite ready for Pebble Beach
Mosquitos were breeding in the footwells!
4.0 liter
4.2 in Eagle
Kindred Spirits, notice the Eagles “sleek” lines!

After filling the long flat tires, and checking to make sure the brakes would, well, slow the vehicle, we put a towel over the seat, and drove the nasty pig home. Then we took a long, long hot shower to scrub off any nasty microbes, or maxi-crobes that we may have been exposed to.

Since the Eagle’s t-case repair, the car has been treating us very well. The old bird always starts, runs, and scares small children wherever she goes. Even with our the nearly bald street tires, the Eagle is unstoppable, even in deep sand! The driving experience is one of complete invulnerability. Nothing can stop the power of the Eagle. Nothing except for the lack of power. The stock 4.2 was rated from the factory at a measly 114hp, and 210 lb/ft of torque. Even with our carburation upgrade, more power was clearly going to be needed.

Since we purchased the Eagle, an incredible resource has been Eagle’s Nest. This wonderful site is to Eagle owners, what Miata.net is to Miata owners. The moderators, and members of the Eagle community have been very helpful, and knowledgeable about all things Eagle. There is even a super cool Eagle history section to the site for those interested in that sort of thing.

On this great site, we learned that a good way to increase power on the cheap is to modify a Jeep 4.0 liter head to fit the 4.2 liter unit found in the Eagle. With some minor modifications, and some exhaust, and intake upgrades, this swap should yield—get this—nearly 100 extra HP! The stock 4.2 liter head it seems, flows about as well as molasses through a straw, while the 4.0 liter head is a nice, modern, efficient head with good flow. Many Eagle enthusiasts go the V8 route, and while it was tempting, we have always been fans of big straight sixes, and this seemed to be a good choice, especially when a 1989 Jeep Cherokee Limited came onto our radar for free.

The ratty old Jeep had been sitting dormant for the better part of 3 years with a broken rear window. Because of this, the interior was better suited to breeding small organisms that human occupation. With a little prodding however, the trusty 4.0 liter fired up, idled, and ran—really well! After filling the long flat tires, and checking to make sure the brakes would, well, slow the vehicle, we put a towel over the seat, and drove the nasty pig home. Then we took a long, long hot shower to scrub off any nasty microbes, or maxi-crobes that we may have been exposed to.

Soon the dirty swapping will happen. Stay posted, and check out Eagle’s Nest when you get a chance.

Did this head ever get fitted? If so what was the result?
