Rebuilding the 3.8L Buick Engine

The Buick 3.8L has evolved from its humble beginnings as a cheap, easy to build, economy motor in 1962 into one of the best pushrod motors in the world. It started in life as a Buick V8 that had two cylinders “missing,” because that allowed GM to machine it on the same line as their

Rebuilding The Chrysler 2.4L

Chrysler replaced its old SOHC four cylinders with an all-new family of SOHC and DOHC engines in 1995. There were 2.0L SOHC and DOHC versions, along with a 2.4L DOHC that was installed in the FWD cars and minivans. Add seven different head castings that came with and without EGR and A.I.R. and throw in

Rebuilding The Ford 4.6L

That’s good news for rebuilders, because most of them are in vehicles that are worth fixing when they need an engine, but there’s some bad news, too. Ford has made a lot of changes over the years, so building the right engine can be a challenge. In fact, if you include the front cover with

Gen III GM Small Block Engine, LS1 Motor for Cars, Trucks

The first generation small block was revised to create the second generation LT1/LT4 that was used for some applications from ’92 to ’97, but the results didn’t satisfy the people at GM Powertrain, so they started all over in ’91 and designed a brand new small block. It’s officially called the “Gen III” motor, but

Rebuilding The Ford 3.0L V6

The 3.0L Ford pushrod motor has been around for nearly 20 years. It was originally introduced back in 1986 and millions of them have been installed in a wide variety of front and rear wheel drive cars and trucks since then. It’s been used in several FWD applications including the Taurus/Sable, the Tempo/Topaz and the

Rebuilding The Chrysler 2.7L

It was rated at 200 HP and it was originally used as the base motor in the Intrepid and Concorde, but it’s been the optional engine in the Stratus and Sebring since 2001 and it will be the standard engine in Chrysler’s new 300 sedan that’s coming out later this year. So, while there are

Rebuilding The Ford 2.0L

  The old 1.9L was modified and upgraded in the process of making it into the 2.0L. The new engine was bored and stroked, it had siamesed cylinders that made the block stronger and quieter, the crank had four more counterweights that made it run smoother, and it had domed pistons for more compression. The

Rebuilding the Ford 4.6L SOHC Engine

The 4.6L was lower, shorter and lighter than the 302, but the base engine made more power than the 302, got better fuel economy and passed all the emission tests without a thermactor pump. Ford called it its “modular” engine because it was part of a whole new family of engines that were intended to

Rebuilding The Ford 3.8L Engine

They needed an economy engine that would fit in their new cars, and they needed it fast. They had a couple of old inline sixes and a small German V6, but none of them were designed for fuel economy or the coming emissions standards, and the 250 cid engine was so tall that it wouldn’t

Ford 4.0L V6 Engine

The original 2.6L engine was replaced by the 2.8L, which was upgraded to the 2.9L and then finally bored and stroked to make it into the 4.0L that was used in the Rangers, Aerostars and Explorers starting in 1990. It was replaced by a SOHC engine from this same family at the end of model
