There are 2 smaller displacement versions of the Continental 602 also. Brockway trucks among others used a lot of 513 and 572 cid engines from that family. I have a 572 with the starter on the passenger side, so don't let that stop you. These engines are excellent, but they do use a lot of gas.

I did know about the smaller 572. I've been able to find several 602s, but no 572s. Sam winer motors sells the 602 for 1500. I spent most of yesterday looking for the physical dimensions on the 602, but no luck yet. Also looked for a bellhousing adaptor plate. I have found a local company I didn't know about the is interested in making a custom plate.

As mentioned, an old military truck gas engine may work well, & there are plenty available. Some used a GMC hydramatic transmission. Maybe buy a whole truck & use the parts you need.

That one won't have the Continental engine in it.

The 2.5 ton GMC built military trucks from the 1950s used a gas GMC 302 cid straight six with a 4 speed GMC Hydro transmission. The gas powered "Reo" style 2.5 ton trucks built mostly in the 1950s used a White/Reo engine about the same size w/ a 4 or 5 speed manual. Most were rebuilt with multifuel engines in the 1960s and 70s which required an OD. The big 602 engines were only used in the 5 ton trucks up to about 1965 or so, with first a Mack diesel replacing them, then a higher hp multifuel until the M800 series came out with a 240 hp Cummins 855 cid diesel. Direct drive transmissions were used on all the gas motors and only the 5 tons w/ the multifuels and OD transmissions used on the other diesels due to the lower governed engine speeds of the diesels and/or the smaller tire sizes.

GMC 302 and 270 engines are of the same family and are generally available both in military trucks and commercial trucks. All the multifuel engines were only used by the military.

The big 602 was governed at 2800 rpm or so, and the I believe the smaller gas engines will go to 3-3,200 rpm.

My truck has what I call true mechanical brakes and only on the rear. When you press on the brake pedal, you move a rod which rotates a cam to push the brake shoes out to the brake drums. There isn't any brakes on the front. I really don't care if the engines can turn higher rpms as I only plan on 30-35 mph tops. Mike

Mike, It appears the bellhousing for the RD450 has a SAE #2 pattern.

Not a popular idea here in antique-land but how about a later fuel-injected engine complete with all controls and its corresponding electronic shift transmission?
Since these things make all kinds of power and wind up past 5000 RPM rear-end gearing becomes relatively unimportant. In my world, a fuel-injected motorhome motor like a Ford V-10, 460 V-8 or a Chevy LS series 6.0l with a 4L80e transmission would be perfect.
Places like Disneyland don’t propel their antique vehicles with antique motors, you shouldn’t either. Time to march into the 21st Century with your head held high!
Just in case you can’t imagine it, later-model truck engines start immediately, idle perfectly in all kinds of weather, seldom if ever stall, and overall provide driveability that an old engine could never match, ever!
I dearly love my old trucks but can do very well without their hiccups.
Going modern diesel is another option but now you are getting into big money.
If you are going to jump on me please remember that your calendar says 2019 just like mine and not everyone is new tech-averse.
I guarantee you that 99% of spectators viewing your fire truck would never guess it had updated power and wouldn’t care if it did. It’s all about the beauty of the antique thing in motion to most people.

On the contrary, the BEST part about old vehicles IS the drivetrain. The sights under the hood, the sounds, the feeling of the vibrations, the idiosyncrasies starting, running, driving and even the smells. It's like a time machine. Without it they are just nice looking, uninteresting, soul-less empty shells. Might just as well be a static display. Modern drive trains are for modern vehicles. I couldn't care less about the nondiscerning 99%. They're the reason modern automobiles have zero class, looking more like silly toys for children. Rather the 1% are the people important to me.

Oh, yes...the stalling, the bucking, the surging, the backfires, the “tight” RPM band, the myriad leaks, the unavailability of parts, the tow truck rides, yes!
Old engines rule! Get me some of that!

Absolutely! Without those things you just have a boring, modern automobile. Great for everyday use, but not interesting.

But many of those things can be improved or cured at the hands of a true mechanic. A dying breed he is, but anyone can learn, if they put their minds to it. Fostering that skill is a big part of the enjoyment derived from most any old machinery. Indeed probably one of the most common traits among the Smokstak community.

And don't forget how much safer modern automobiles are. They are incredibly crash worthy. It helps to add seatbelts, but old cars can never be as safe as their modern counterparts. So, if you want to have a "better" vehicle, I think safer is far more important than just easier to drive or more reliable.

“Great for everyday use..”.what a slam.
Again, I really love and cherish these old engines but if you are trying to interface with modern roads, vehicles and drivers you need modern motivation, at least “under the skin”. Updating drivetrain is a great start. What new engines lack in soul they more than make up for in great driveability and serviceability.
In my opinion you are shorting yourself if you don’t at least consider an engine/trans from THIS millennium. You know, 2000+?
I swear I won’t rat you out to the purist. I think there’s only one left.

Two different worlds.
Military trucks and fire trucks are designed with toughness and dependability as the number one requirement. I've yet to see one with a 5000 RPM screaming V8 in it. I'd love to see a fire pumper truck with a Chevy LS in it trying to run for 20 hours at full throttle putting out a fire. It would need a scatter shield to catch the flying parts. A Continental 602 can do that over and over again. Now, on race day at the 1/4 mile, the LS would outshine the Continental big time. It's all about using the right tool for the job.

I'm definitely NOT putting a modern engine in a fire truck that is 91 years old !!!! It just isn't right. I'm going to stay gas. Diesel would be a bigger pain in the #*@$????;(&@. My truck has true mechanical brakes on the rear only. Going fast is not an option.

I have a good friend that has lots of old vehicles, and all can be running in no time. It is how you care for them.I personally like the sounds of the older cars and trucks. There isn't anything made in the past 25 years that even comes close. I do admire those who preserve the past weather it's a model t or a true mussel car of the 60s. Everyone has a passion for something in this world, and mine is preserving my fire truck to the best of my abilities. Both of my daughters have helped at times as well as my wife. The engine issue is just a hurdle I need to get over. Once I get over that one, there will be another. In the end, I will have a good running fire truck to drive and enjoy with my family and friends for years to come. Thanks Mike

“Abomination” is quite a word...are you sure you don’t want to use “Armageddon” or “apocalypse”?
No wonder we people are shooting each other in droves. We are always amping up the rhetoric.
Just say that “a modern engine in a antique vehicle is a bad choice”.
In many cases I would agree, but not on street-driven vehicles.
If you are routinely driving your stock old-Timey rig in rush hour traffic YOU are the abomination.

I work in a poor little farm town. There’s a farmer here who converted his beautiful 1940s Diamond T 2 ton truck to SBC. He only uses it to haul fruit or equipment during the growing season. When he drives by everyone is all smiles and thumbs up. His exhaust sounds so sweet, too!
Is HE an abomination? Should I go tell him?
Without that “repower” the Diamond T might’ve been junked...?
Can you begin to see my point?
I see you passion and raise it 1000x!
DF!
