How do I fit an LS in place of my V-6 or four-cylinder?
LS engines are surprisingly small. Their overhead valve configuration makes them compact for their displacement compared to DOHC V-8 engines that have massive heads that can prove too wide for many applications. LS engines have been shoehorned into everything from Miatas to Geo Trackers, so there’s no reason why they can’t fit into any mini or fullsize truck. The real variables are motor mounts and headers that will clear your frame and suspension. If you’ve got a common platform for swaps, like an S-10 or an ’88-’98 Chevy, then you’re in luck; Hedman makes S-10 LS swap headers, and Summit carries Schoenfeld headers for swapping an LS engine into ’88-’98 Chevy/GMC truck or SUV. Jags that Run and Current Performance can also help you out with motor mounts and wiring harnesses, but just because you don’t have a Chevy doesn’t mean you can’t easily drop an LS in place. Advance Adapters makes conversions to mount LS engines to Toyota and Jeep transmissions as well. Check out our sources at the end of the article to help with your specific questions.

Here’s a checklist of items you’ll need for a conversion, besides the long-block, of course.

• Engine control module (ECM)
• Wiring harness, including:
Injector harness (varies by injector)
Cam Position Sensor, gray sensor located on the top rear in Gen III, black sensor on the timing cover on a Gen IV.
Reluctor wheel. Gen III (LS1 and older truck Vortec engines) = 24X wheel, Gen IV (LS2 and LS3) = 58X wheel. Make sure the wheel matches the computer, or your engine will be so confused it won’t even start.
• Throttle pedal, necessary for any drive-by-wire throttle body.
• Bellhousing/Scattershield
• Oil pan.
Note: A factory Camaro pan is a good choice for most swaps, as its shallow rear sump makes fitment easy in most applications
• Motor mounts
• Headers
• Fuel pump
• Cooling system with sealed overflow bottle/container
• Dyno tuning shop to get your new computer dialed in and running its best

Now that we’ve shown you the basics, we’ll also show you some great dress-up and go-fast goodies for your engine swap. If you’re putting an LS engine into a truck that was designed to fit an LS, header choices are plentiful. When we swapped our V-6 to a V-8, we picked up these SLP shorty headers from Stylin’ Trucks and they fit perfectly. But even if your truck wasn’t designed for an LS, plenty of companies make headers that will make your swap a whole lot easier. Check out Jags that Run, Schoenfeld, or Hedman.

Adding horsepower means adding improved cooling as well. Flex-A-Lite makes radiators and fans of all sizes to keep your engine cool no matter what the application, and we ordered it directly from Stylin’.

Aluminum radiators and fans.

An overflow tank or bottle is a requirement as LS engine’s don’t use a traditional radiator. We picked this one up from a salvage yard but dressed it up with a paintable plastic cover from Stylin’.

With the COP (coil on plug) ignition systems that come equipped on LS engines, it leaves much to be desired for show points. We covered up these unsightly coils with billet plates from, you guessed it, Stylin’.

A few final pieces of the dress-up puzzle was the customization of a paintable engine cover and a new Spectre air intake, also from Stylin’. Whereas the engine and coil covers aren’t required for an engine swap, they sure made this show truck look great with its new 5.3L under the hood.
