Whether you would like to achieve better performance out of your vehicle or are working on a classic car restoration, you may be considering an LS engine swap. The draw of substantially increased power with a LS1, LS3 or another GM engine may be appealing, but determining everything that you will need while completing your LS engine swap may be a challenge. Be sure to ask all the right questions before you start so that you can have the parts on hand that you need.
Top Questions To Ask When Doing An LS Engine Swap
An LS engine swap can improve the durability and performance of your vehicle, but it comes with its share of questions. Depending upon the engine that you choose, you will also need to be sure that you have the correct mountain plates, oil pans, and other parts to keep the vehicle working smoothly after the swap is complete. Take some time to ask the following questions so that you can be prepared before, during and after your LS engine swap.
What Engine Is Best For An LS Swap?
A number of factors go into choosing an engine for a swap, but one of the primary determiners is how much you can afford. The right engine for your LS swap is one that combines affordability and performance that suits your goals. Many people strive to acquire a brand new LS3 or other high-end parts, but they are not the only options that are worthwhile. Choose an engine that fulfills your needs while staying within your budget.
Which LS Engine Mounting Plates Are The Best?
The type of mounting plates that you will need for your LS engine swap can be informed by the type of engine you choose, but you typically have a variety of options. In general, it is best to opt for name brand plates so that you can benefit from their known reliability. From there, the type of mounting plate you choose will come down to your personal desires; some options offer slots that enable you to customize exactly how your engine sits within the car.
Which Oil Pan Do I Need For My LS Swap?
Most oil pans will work with most LS engines. The greater concern is selecting an oil pan that will fit within the specific car you are working with. Above all, the pan must clear the chassis as well as the stroker, if you choose to use one. If you acquire an aftermarket oil pan, be aware that it will not come with a windage tray, so you will need to purchase one separately.
What Exhaust Will I Need For My LS Swap?
Multiple options are available for exhaust. The longer the tube, the more power it can make, but both budget and car shape will impact the choices you have available. The exhaust must clear the chassis and subframe, as well as your steering equipment.
What Accessory Drive System Do I Need For My LS Swap?
The accessory drive that you choose for your LS swap will likely come down to what fits within your budget. With dozens of options to choose from, your primary concern should be ensuring that all your features continue to work; GM AC compressors will not work with the majority of aftermarket ACs, and car-type intake manifolds cannot interface with factory truck serpentine systems.
What Fuel System And Tank Will I Need?
The type of fuel system you select will depend upon the engine you chose. Carbureted LS engines do not require any equipment that would not already be needed for a standard small- or big-block engine. If you choose EFI, a sump or baffled tank is the right choice. Be sure that the fuel pump can supply at least 60 psi in order to ensure proper operation.
