Gen III/IV engines have the same basic requirements for their exhaust system as other automotive engines, but these high-performance engines have specific EFI system requirements that must be met for the system to perform properly. The LS engine requires at least one oxygen sensor (as many as four), which must be placed a minimum of […]
How to install a Fuel System into an LS-Swapped Chevelle
Installing a fuel-injection system on a classic muscle car that was originally equipped with a carbureted fuel system requires careful planning and component selection. Many components that go into a fuel system, including the tank, fuel pump, lines, fittings, and filters, must be replaced or upgraded. Simply installing an electric fuel pump does not work. […]
Choosing the best motor mounts for a Chevelle LS Swap
The key to any swap is getting the engine into the chassis. This can be easy or it can take weeks to figure out, it all depends on the car. The 1968– 1972 A-Body vehicles are easily converted to Chevy small-block frame mounts, but the earlier 1964–1967 A-Body cars are not as simple. General Motors […]
How to Pick the Right Oil Pan for Your LT Swap
There are a lot of choices when selecting an oil pan for your LT-engine swap, make sure you get the right one! Regardless of the vehicle, the oil pan is often the most difficult obstacle to overcome in an engine swap. Unlike the LS platform, which has no less than 10 oil pan variations from […]
How to Start Swapping an LT Engine Into Your Car or Truck
The main concerns for LT swaps are fitting the oil pan, accessory drive, power steering, and fuel system. Another issue is the exhaust (mainly headers or manifolds) because the head design for LT engines is different from the LS series, and there are simply not very many options for swaps, so you need to get […]
Camaro and Firebird LS Swap: Initial Start-Up Guide
I am pretty sure that by now you are ready to turn the key and fire up the engine. Now take a deep breath and slowly walk away from the car. Yes, that’s right. Walk away. This may sound counterintuitive because you’re itching to get your LS-powered F-Body car on the road. However, the last […]
Camaro and Firebird LS Swap: Exhaust and Induction Guide
Often the exhaust portion of a build is left to the very end when everything is bolted up; it’s often quite literally an afterthought. As I stated in Chapter 2, a sound strategy is to select the engine mounts, transmission crossmember, headers, and related parts as a kit. The header routing and clearance of the […]
Camaro and Firebird LS Swap: Wiring Guide
As with other LS components, a massive number of computercontrol, harness, and electronic equipment options exist for this popular engine platform. Most swappers adapt the factory electronics to the particular F-Body, but installing aftermarket controllers are certainly an option. If you don’t want to adapt the EFI and drive-by-wire gas pedal technology to your F-Body, […]
Firebird and Camaro LS Swap: Transmission Guide
You have a universe of transmission options for swapping an LS into an early F-Body, and like other components of your equipment package, the transmission you select should be based on application. Most owners stick to a transmission that has a compatible bolt pattern for the LS because it’s convenient and many superb transmissions simply […]
Firebird and Camaro LS Swap: Cooling System Guide
A high-performance LS engine generates much more heat than a Chevy Gen I small-block engine or a Pontiac V-8 that originally came in many of the F-Body cars, so you need a cooling system that effectively and efficiently dissipates and manages the heat. Therefore, you need the correct components, adequate capacity, and proper calibration for […]
