Godzilla Ford Motor

Curious, what is the final opinion of the new Godzilla motor? What makes it better than the V10? All opinions welcome.

That's hard to answer unless you have an Apples to Apples comparison, e.g., same rig, same transmission, same rear axle and same weight.....

But, for an opinion, yes, the new 7.3L Godzilla has more power/torque/pulling.

The second part of your question... "is it better than the V10"... well, only time will tell.

The 7.3L is base on solid design from the Winsor block, push rod (but with variable timing), 4-bolt main, variable oil pump/pressure, forged rockers, and built to handle way more power (HP and Torque) with the OEM parts. Engine tech have already had the 7.3 over 1100HP with OEM piston, bearings, pushrods, heads, etc.

Thank you for your response. I would be interested in how they produced that much horsepower and how useable and reliable the motor is at that point. I am overall happy with the V10 but could use a little more pulling power when in the Rockies pulling my Jeep. They tell me it does not hurt the V10 to rev it up to 4,000 at times to pull hills…..scares me a little. As you said time will tell. Question: Why won’t they sell a front engine Class A with a Cummings??? Seems to me it would sell.

Engine comes from the Chassis Builder..... for the Ford F53 chassis.... I believe the real question is, why doesn't Ford offer their Diesel PowerStroke engine in the F53 chassis?

But the new 7.3L V8 is now push-rod and produces much more power at much lower RPMs than the V10

The only diesel I'm aware of from Jayco is the Super C Class from Frightliner.

Here's a pretty good post regarding the change in engine... https://www.rvnetwork.com/topic/1351...or-class-a-mh/

You are absolutely correct. My question should have been why not the Power Stroke? I would bet the F53 chassis is offered with the Power Stroke in the trucking world.

Likely because the cost of a diesel makes the cost of all of it exorbitant.. plus the potential issues with warranty with the diesel motor...

That is only a guess... gas motors are cheaper, more payload, and less maintenance (fuel filter/oil changes/def...) than a diesel...

No, Ford does not offer a Diesel in the F53... here's the link: https://www.ford.com/commercial-truc...f53-motorhome/

I have a few guesses why.... i.e., the added cost and therefore the price point for the end product and the V8 handle most everything for the intended purpose of the F53 chassis.

You are exactly right. I used to try to sell Campers at Camping World. People come in expecting a Cadillac CTS-V unit for a Chevy Spark price.

Do you have the Godzilla Motor in your Precept? Do you tow anything?

Yes, I do. and Yes I've towed. It's certainly no diesel, but gets the job done.... it's just slow going up hill.

If towing is a big concern, then diesel would be the way to go, but is the +$100k worth the speed increase? It all depends on your requirements and "expectations".

Having had 5 Class ‘C’ units w/ the V10, I can easily say the Class ‘C’ I just test drove with the V8 was peppier and quieter. I was impressed !

Don't forget about the Melbourne built on the MB Sprinter chassis.

Thank you again for your response. I am certainly not interested in the expense of a DP. I am retired and am in no hurry. My ONLY concern is reliability…. If my V10 is happy screaming at 4,000 RPM and getting it done, I am OK with that. I am in Colorado. I just went through Parshall yesterday heading to Golden. That pass was 11,3000 according to my GPS. We went over at a reasonable with no problem. If I can do that for 100,000 miles, I am totally satisfied. I thought Rabbit Ears Pass earlier in the day. I knew that was high (9,300) so I had the wife drive the Jeep and I drove the Coach.I towed the Jeep through Parshall. To be fair , there was not that much difference in performance of the coach other than a little speed. I would really like to drive a similar coach with the Godzilla motor. Ford has stated they are interested in durability with the new motor, not numbers…..works for me.

Have you had any mechanical issues with the engine?

I have a 2021 F350 with the 7.3 Godzilla / 10R140 Trans and 3.73 rear - It tows my 9,000 pound camper without issue. I agree its not a diesel but for the amount of times I tow which are usually 2 - 2 week trips over the summer and a dozen or so weekends the rest of our camping season I simply couldn't justify the added up front cost of a diesel not to mention the increased maintenance expense.

I traded my 6.2 F250 for this one simply because of the insane trade value the dealer gave me. The 6.2 struggled with steep inclines a lot more than this truck does. Overall, I am quite happy with the truck.

Love my 2021 F250 7.3 gasser! Tows my 284BHOK flawlessly.

There were some issues with the first year production but those seem to have been worked out.

Love my truck!

Too early for a final opinion. Use to be manufacturers tested engines before putting them out in the market. Now it's the consumer who does their testing for them. As a common problem surfaces is when they make a corrective change.
That said......I would jump on the 7.3 in a heart beat.
I would also love to see the PowerStroke on the E450 Class C chassis. It would be pricey as heck but fill the niche of those who want a Class A Diesel for the performance but don't want the size of a Class A.

The Godzilla motor doesn't have a very high bar to leap over the V10. The "10" is an overreving slug which always longed for both horsepower and torque. I had (2) V10's in class C's before going GM Workhorse for my new '05 class A.
