Can You Swap a 5.7 Hemi With a 6.4 Hemi?

There are a lot of different ways that people like to modify their cars and trucks. Some people like to change the appearance, while others like to change the performance. And then there are those who like to do both.

When it comes to engine swaps, there are a lot of different options out there. But one question that we get a lot is whether or not you can swap a 5.7 Hemi with a 6.4 Hemi.

Are 5.7 And 6.4 Hemi the Same?

The short answer is no, the 5.7 and 6.4 Hemi engines are not the same. The 5.7 Hemi was introduced in 2003 as a replacement for the 5.9 engine, while the 6.4 Hemi was introduced in 2009 as a replacement for the 6.1 engine. Both engines share some similarities, such as displacement (5.7L for the 5.7 and 6.4L for the 6), but there are several important differences between them.

How Much Horsepower Does a Stock 6.4 Hemi Have?

Assuming you are referring to the 6.4L Hemi V8 engine found in many Chrysler products, this engine typically produces between 410 and 475 horsepower. However, this will vary depending on the specific model and trim level that the engine is found in. For example, the 2019 Dodge Challenger R/T Scat Pack 1320 has a 6.4L Hemi V8 engine that produces 485 horsepower.

Is the Hemi 6.4 a Good Engine?

The 6.4L Hemi V8 engine is a great engine. It has plenty of power and torque, it’s very reliable, and it gets good fuel economy. It’s a great engine for towing and hauling, and it’s also a great engine for daily driving.

The only downside to the 6.4L Hemi V8 engine is that it’s a bit noisy, but that’s about it.

5.7 to 6.4 Hemi Swap Ram 2500

If you’re looking to upgrade your Ram 2500 with a Hemi engine, you’re in luck. The 5.7 to 6.4 Hemi swap is a popular modification that can give your truck a serious boost in power and performance. There are a few things to keep in mind if you’re considering this swap.

First, the 6.4 Hemi engines are significantly more powerful than the 5.7, so make sure your drivetrain and suspension can handle the extra power. Secondly, the 6.4 engines are taller than the 5.7, so you’ll need to modify your engine bay to accommodate the larger engine.

5.7 to 6.4 Hemi Swap Ram 1500

If you’re looking to add a little more power to your Ram 1500, then a Hemi swap is definitely something to consider. The 5.7L Hemi V8 engine is found in many different Chrysler vehicles and offers a significant increase in power over the standard 3.6L V6. While the swap itself isn’t overly complicated, there are a few things you’ll need to take into consideration before making the switch.

First and foremost, you’ll need to decide which Hemi engine you want to use. The most common option is the 5.7L, but the 6.4L is also an option if you’re looking for even more power. Either way, you’ll need to source the engine from a donor vehicle (most likely a salvage yard).

You’ll also need all of the appropriate mounting hardware and wiring harnesses – which can be sourced from Mopar or aftermarket suppliers. Once you have everything gathered together, the actual swap process isn’t too difficult. However, it’s always best to consult with a professional mechanic or fabricator if you’re not confident in your own abilities.

5.7 to 6.4 Hemi Swap Charger

Looking to swap out your 5.7L Hemi engine in your Charger for a 6.4L Hemi? Here’s everything you need to know! The 6.4L Hemi engine was first introduced in the Dodge Challenger and Charger in 2011.

It was then later used in the Jeep Grand Cherokee and RAM 1500 truck lineups. This engine quickly gained popularity among Mopar fans due its high power output and reliability. Now, many people are looking to swap their 5.7L Hemi engines for the more powerful 6.4L Hemi.

If you’re one of these people, here’s what you need to know! This swap is not a bolt-on affair and will require some custom work. The most difficult part of the swap is mating the new 6.4L engine to the older 5-speed automatic transmission found in pre-2011 Chargers (6-speed automatics were introduced in the 2011 model year).

A popular solution is to use an aftermarket 4×4 adapter plate, which allows you to bolt up a modern 4×4 transmission (like the 8HP70) to the back of the 6.4L Hemi engine. This gives you much more transmission options and opens up possibilities for future upgrades down the road. Another consideration is that your old 5.7L engine mounts will not work with the new 6.4L engine – you’ll need new ones!

There are a few different companies that make aftermarket mounts specifically for this swap, so do your research and choose a set that best fits your needs/budget (we recommend using polyurethane mounts for added durability).

Some Jeep and Dodge owners with a 5.7 Hemi engine might be wondering if they can swap it out for a 6.4 Hemi engine. While the two engines are similar, there are some important differences to keep in mind before making the swap. The first difference is that the 6.4 Hemi is a much newer engine than the 5.7 Hemi.

It was introduced in 2009, while the 5.7 Hemi has been around since 2003. The 6.4 Hemi is also more powerful than the 5.7 Hemi, with 410 horsepower compared to 375 horsepower. Another difference is that the 6.4 Hemi uses a different cooling system than the 5.7 Hemi.

This means that you’ll need to get a new radiator and hoses when you make the swap.
