"How will it fit?" is the question I get most with my Porsche 911 LS swap project. I usually shrugged my shoulders in response, because I was clueless how an American pushrod V8 could fit in a space made for a small European flat six. Now that my Corvette engine is bolted in, I finally know how it fits -- and the best way to describe the process is that it's similar to kids playing on a seesaw.

I will explain the seesaw fitment method in a bit, but first I want to cover one of the surprises with this build. In my previous video, I removed my dead Porsche flat-six engine from the chassis. Once the engine was out, it looked huge! In comparison to the Chevy 6.0-liter V8, the stock 3.4-liter flat six appears to be wider, as well as longer-- and since the intake is quite tall, there's not much of a height difference, either.

The main advantage the Porsche engine has when it comes to fitting in the cramped rear of the 911 is its accessories, which are smaller by comparison to the V8's -- but the kit I ordered for this project solves this problem. Included is a new smaller alternator, water pump and AC compressor with slimmer bracketry -- which makes the LS as skinny as possible and relocates the alternator below the "V" of the V8. The power steering pump is eliminated entirely in favor of an electric power steering kit -- comprised of Toyota parts.

Also included is a new motor mount arm, which bolts to the front of the engine -- whereas, in a Corvette, the motor sits on its mounts bolted to the block. In my 911, the LS will be literally hanging from its heads.

Even with the slimmer parts, the chassis of the 911 still needed some trimming around the bumper bracket. My mechanic, the car wizard, sawed away at my 911 while I was away -- partially to spare me the agony of witnessing the hackery, but also to keep me away from his power tools. He figured I will need all of my limbs intact to drive this Porsche when it's finished.

A gorgeous piece of machined aluminum is included with the kit to adapt the Chevy V8 to the Porsche transmission. Also included is a flywheel and clutch, the latter of which appears to be supplied by Ford.

If you're not cringing yet, you will be when I describe how to fit an LS V8 in the back of a 911. Like a normal Porsche, the chassis is lowered onto the drivetrain -- but the motor mount configuration with the LS swap makes things more difficult. The mounting bracket has to sit above the mounting points to the body, which are located at the same height as the Porsche's taillights. Somehow, the engine must be maneuvered over these mounts, which required us to tip the entire drivetrain on its side, lift it in place, and then repeat with the opposite end.

The whole process resembled kids playing on a seesaw, or tipping over a large piece of furniture to fit through a skinny doorway. Now that my LS is fitted, the car wizard has to figure out how to get it running. It's certainly going to take some wizardry to get the Porsche computers to interact with the Chevrolet components so we can bring this monster to life.
