Can You Swap A 5.7 Hemi With A 6.4 Hemi

Hey there, gearhead! Grab a seat, let's chat about something that's been buzzing around the garage lately - swapping a 5.7 Hemi for a 6.4, yeah?

First things first, why the heck would you wanna do that, right? Well, let me tell ya, the 6.4 Hemi, or the "Apache" as some like to call it, packs a serious punch. We're talking around 470 horses and 470 lb-ft of torque. That's like having a tiny, angry dinosaur under your hood.

So, Can You Swap?

Alright, let's get down to business. Can you actually swap a 5.7 for a 6.4? The short answer? Yeah, you can. But hold your horses (pun intended), it's not as simple as bolting on a new engine.

The 5.7 and 6.4 Hemis share some similarities, sure, but they're not exactly twins. The 6.4 is longer, heavier, and has different mounting points. So, you're gonna need some custom fab work. Think of it like trying to fit a V8 into a four-cylinder bay - it's doable, but it ain't pretty.

What's Involved?

First off, you're gonna need to fab up some new engine mounts. The 6.4 is heavier and has different mounting points, so you'll need to make sure it's secure. You'll also need to extend your oil pan, as the 6.4 sits lower than the 5.7.

Then there's the exhaust. The 6.4 needs a different manifold and catalytic converters. You might need to fab up some custom pipes to make it all fit. And don't forget about the computer - the 6.4 needs a different ECU and sensors.

Oh, and let's not forget about the transmission. The 6.4's torque can be a bit much for some transmissions, so you might need to upgrade that too. It's like trying to put a cheetah in a hamster cage - it'll work, but it's not ideal.

Is It Worth It?

Alright, so it's a lot of work. But is it worth it? Well, that depends on what you're after. If you're chasing raw power, then yeah, the 6.4 is gonna give you a serious kick. But it's also gonna cost you - in time, money, and probably some sleep.

And let's not forget, the 6.4 isn't exactly known for its fuel efficiency. It's like a hungry teenager - it wants food, and it wants it now. So, if you're looking to save on gas, this might not be the swap for you.

But hey, who are we kidding? We're not doing this for fuel efficiency, are we? We're doing it because it's fun. Because it's a challenge. Because it's a chance to make something awesome out of something good.

So, Should You Do It?

Well, that's up to you, isn't it? If you've got the time, the money, and the know-how, then yeah, go for it. Just remember, it's not gonna be easy. But then again, nothing worth doing ever is.

And hey, if you do decide to take the plunge, drop me a line. I'd love to hear how it goes. Who knows, maybe I'll even come by and help you wrench on it. Just promise me one thing - no matter what, have fun. That's what this is all about, right?
