Editor’s Note: We’re back with Part Two of Project LS Next, a 440 cubic inch LS engine based on Dart’s LS Next iron block and built by Mike Mavrigian at Birchwood Automotive. In Part One, we covered the block prep, the rotating assembly, and camshaft installation. This round is devoted to the oiling systems, valvetrain,
Sixty-some years ago, before our favorite four-wheel-drive vehicle earned the name Jeep, the Army’s 4WD ¼-ton scout vehicle was given the designation of “GP” for General Purpose vehicle. It was given this designation because the Army needed a small, agile vehicle that could do any job it was called upon to perform: carrying four soldiers, mounting a
Editor’s Note: Mike Mavrigian of Birchwood Automotive is back with another cool engine build. This one is a 440 cubic inch LS engine based on Dart’s LS Next iron block.

In Part One of YJ Rehab, we showed you how to restore the suspension and upgrade the fuel system on a 1994 Jeep Wrangler Sahara. In this exciting episode, we’ll show you how to rebuild a set of rear drum brakes. Would we have preferred to do a rear disc conversion? Yes. But several came

And with good reason—a production Coyote makes 435 horsepower and 400 ft.-lbs. of torque, and they’re readily available in crate engine form.

That was a while ago, and life and weather conspired to put the project on the proverbial back burner. But now that both have returned to some sense of

It’s time to hit the highway for a little summer adventure. Our getaways often include four-wheeling on new and distant trails, and that means towing our Jeep behind a motorhome or some other tow vehicle. When it comes to choosing a towing method, you’ve got a few choices: flatbed trailers ($2,500+), tow dollies ($1,000+), and tow bars ($125). Obviously, the
