Ford 6.2, 7.3, & 6.7 Power Stroke Engines
The newest line-up of Ford Super Duty F-250 and F-350 trucks offer three main engine choices. Ford 6.2 and 7.3 gas engines may be a compelling choice for some – even over the highly capable 6.7 Power Stroke diesel. Each of these engines come with their own benefits and downfalls. We’ll be very up-front to kick this off. If performance and towing are the ultimate goal the 6.7 diesel takes the cake. However, it’s a $10,000+ engine option and not everyone needs AS MUCH as the 6.7 has to offer. In this article, we discuss the pros and cons of each engine when it comes to Ford 6.2 & 7.3 gas engines vs the 6.7 diesel.
6.2L & 7.3L Gas vs 6.7 PS Specs
Specs for the Ford 6.2 Boss vs 7.3 Godzilla vs 6.7 Powerstroke engines are as follows:
*Based on 2021 models. Exact specs may vary by year.

|Block Material||Cast Iron||Cast Iron||Compact Graphite Iron|
There’s no point in dancing around this one. Ford’s 6.7 Powerstroke turbodiesel is the ultimate engine for performance and towing. The 6.2 and 7.3 gas engines simply cannot compete with the torque the 6.7 diesel has to offer. That said, both the gas engines are capable performers and the Powerstroke is simply overkill for many F250 and F350 owners. We’ll circle back to this topic later on.
Otherwise, these are all strong engines. Cast iron engine blocks on the Ford 6.2 and 7.3 gas engines are very strong and durable. Power output for the 6.2 Boss and 7.3 Godzilla gas engines are pretty low for their size. However, this also helps with strength and longevity.
The Ford 6.2 gas vs 7.3 gas vs 6.7 Powerstroke specs speak for themselves. Diesel engines offer dominant performance, but even the weaker 6.2 gas engine has solid specs. Ford 7.3 V8 gas Godzilla engines offer a nice middle ground. It offers a little more performance for those who need it without being as overkill as the 6.7 diesel.
Ford 6.2 Boss Engines
Ford 6.2L gas engines – also known as the 6.2 Boss – are the standard option for F-250 and F-350 Super Duty trucks. The 7.3 gas vs 6.7 Powerstroke both come with price increases. As such, the 6.2 V8 is an excellent cost-effective engine. With 385hp and 430 lb-ft it offers plenty of performance and towing capability for most.
Additionally, the Ford 6.2 has been out since 2011. It’s prone to its fair share of common problems – as is any engine. However, Ford 6.2L engines have proven to be durable, reliable workhorses. There are plenty cases of these engines holding up beyond 300,000 miles with few issues.
Ford 7.3 Godzilla Gas Engines
This is probably the engine that gets the most hype as of now. The 7.3 Godzilla gas engine is the newest addition to Ford Super Duty trucks. It’s about a $2,000 option, so there’s that to consider. However, Ford 7.3 gas engines help fill a gap between the 6.2 gas vs 6.7 Powerstroke. Not everyone needs the insane 1,050 lb-ft of torque – it’s simply overkill for some. 7.3L Godzilla engines offer a 45hp and torque advantage over the standard 6.2 Boss.
As a newer engine there isn’t as much known about reliability and longevity. However, the 7.3 gas engine has a low power output relative to its size. That should help with overall durability of the engine as it’s not stressed. We suspect the Ford 7.3 Godzilla will offer similar longevity to the 6.2 Boss.
Ford 6.7 Powerstroke Turbodiesel
Last but not least – the highly capable 6.7 Powerstroke diesel engine. We’re obviously a little biased towards diesel engines here. However, we understand diesel engines aren’t for everyone. Notably, Ford 6.7 Powerstroke engines offer more performance than most will ever need. If you don’t need more than the gas engines it’s tough to stretch to the $10,000+ Powerstroke price point.
Diesel engines are well known for their exceptional longevity. It’s not uncommon for the 6.7 Powerstroke to push well beyond 300,000 miles. Unfortunately, newer diesel engines are subject to strict emissions equipment. A lot of this can be problematic and deleting emissions equipment is illegal. Nonetheless, the 6.7 Powerstroke is still a reliable engine that offers truly incredible specs.
6.2 Boss vs 7.3 Godzilla vs 6.7 Powerstroke
That’s really all there is to the 6.2 & 7.3 gas vs 6.7 Powerstroke comparison. If you need the ultimate performance and towing then the 6.7 Powerstroke is the clear choice. Those looking for less can then decide between the 6.2 Boss and 7.3 Godzilla V8 gas engines. Ford 7.3L engines come at a slight premium, but the price is reasonable.
Most can stop reading here. The rest of this article may be a little repetitive. However, for those still unsure we’ll dive deeper into some 6.2 vs 7.3 vs 6.7 topics.
Ford Gas vs Diesel Engines Reliability
We touched on reliability of each engine quickly above. Diesel engines are often known to provide better longevity compared to their gas counterparts. However, modern emissions equipment does work against diesel engines. The days of the legendary 7.3 Powerstroke and 5.9 Cummins are long gone. Modern diesel engines like the 6.7 Powerstroke often run into emissions equipment issues. They’re still reliable engines that provide excellent longevity, though.
When it comes to the Ford 6.2 gas vs 6.7 Powerstroke we suspect the diesel will outlast the gas engine on average. That said, the Ford 6.2 Boss is still a solid, reliable engine. The 7.3 Godzilla is still too new to say for sure, but it should follow in the footsteps of the 6.2 V8.
Assuming all engines are maintained the same the 6.7 Powerstroke has the reliability and longevity advantage. The 6.2 vs 7.3 gas vs 6.7 Powerstroke are still all reliable engines. Sometimes it simply comes down to luck of the draw. Below are links to a few articles about these Ford engines common problems.
6.2 Gas vs 7.3 Gas vs 6.7 Powerstroke Towing
There are a lot of factors that affect Ford F-250 and F-350 towing capacity. As such, the following numbers are a rough range for each engine:
- 6.2L Gas V8: 12,000 – 16,700 lbs
- 7.3L Gas V8: 13,000 – 21,200 lbs
- 6.7 Powerstroke: 14,000 – 22,800 lbs
What these numbers don’t show alone is that the 6.7 Powerstroke also has a big advantage in GCWR. This is going to be repetitive. However, the towing capacity and CGWR show the 6.7 Powerstroke is the ultimate engine for towing. Its massive torque advantage is also going to make towing that much easier.
That’s not to say the 6.2 and 7.3 gas engines aren’t formidable competitors. They still offer more towing capacity than most diesel trucks from 10 years ago. If you’re not planning to consistently tow 15,000+ lbs in harsh conditions then the 6.2 and 7.3 will get the job done.
F-250 & F-350 Fuel Economy (MPG)
This somewhat ties into the above discussion with towing. MPG is going to depend on tons of different factors. The Ford 6.2 gas vs 7.3 gas vs 6.7 Powerstroke engines are all pretty close in fuel economy. When it comes to towing heavy loads you might see better economy with the 6.7 diesel, though.
The massive low-end torque from the diesel helps you get moving without needing a lot of RPM’s and stressing the engine. As such, the 6.7 Powerstroke likely gets the win from those who demand the most. Otherwise, all of these Ford engines in the F-250 and F-350 deliver similar MPG.
