Gotta love that deafening roar those old n/a industrial v8 diesels. Nothing was louder then a screaming idi 7.3 international can hear them for miles like the old 2 stroke Detroits. Hearing these old 70s and 80s v8 diesels makes you realize how horrible and cheap new diesels sound.

If you want to remain in style, call them the 420 and 444 internationals ... only Ford named them by their stupid metricized displacement. Cat 3208 is 636 cubic inches, the internationals are 420 and later 444 ; the electronic ones that Ford called the Powerstroke are 444-E
@@castirondude And we have 1994 Blue Bird International Bus with that same engine and decal...And it HAD the AT-545 - It has been replaced somewhere with the AT1545 (lockup style) transmission.
Not alot of RVs are big enough for that size engine. Too tall, oil pan to valve cover, not to mention they weigh over 5000 lbs. Who really needs that much horsepower in an RV ? Better fuel mileage would be a better feature.
Agree, I have a 3406 in a semi and it's an amazing engine. 430 HP if memory serves. I have a later Wanderlodge with 500 HP Detroit 8V92 but it has so little starting torque it's pretty pathetic. I'm working on putting a Cat 3412 in it now
As far as more gears and closer together...the MT654CR is a non-electronic 5-Speed that works better for that. (Many wanderlodge guys are running 2 speed rearends) You can have your hwy gears and your hill gears.
The Allison AT54x is a 4 speed non-lockup transmission. The MT64x is heavier duty and has a lockup converter that's always locked in 3rd and 4th gear. The locking converter saves some fuel and heat but sometimes pulling up the hill that makes it even harder to keep the engine in a usable power band. The MT65x is the same except the first gear is lower. 2-5 gear are the same as 1-4 on the 64x. Doesn't help on the highway. It just helps you get started from a standstill.

Looks like a trip to a cat specialist is in order, maybe different injectors, this motor came in 3 configurations, and your motor in theory could produce 375 or 435 hp. Of course you know that the engine has no sleeves so an inframe rebuild is out of the question, and a newly rebuilt motor is a chunk of change.
Can't do much with the NA. The best these motors did was 300 hp in the late 80's with different pistons and rings and an aftercooled turbo. More than that was strictly marine. The Cat is sold and this video is to compare the performance before and after I install the Cummins ISM.
@@couttsw I believe the emissions retrofit only applies to commercial trucks 14,000 lbs and up ; even if the RV is heavier than that it would be exempt because it's not a truck. You should still leave California though.

@@martinbuysabus932 I wonder if the auto sucks a lot of power? I had a 1964 Prevost, with 6V71, and climbing that exact hill (I'm in Maple Ridge) I can do 40km with a little pedal to spare. That engine did have 70-size injectors which puts it around 250 hp. My weight was 11,000 kgs.
I never climbed an 11% hill. But I think a Chevy 454 gives you 350-450 HP stock and probably not much worse mileage. I have been on a CAT watching/reading binge since youTube suggested a boat video with dual 3208s. Heavy, low power, low torque, poor fuel economy is what I came away with. Built in the days of sub-$2.00/gallon diesel.
The Cat 3208 is 636 cubic inches so it's a real thumper compared to the 454. The 454 needs lots of RPM's to make higher HP numbers. It's uncomfortable to run 5000-6000 rpm for long periods of time. My uncle had one and it threw a rod eventually from running 5000+ rpm for hours and hours.
My 1993 Wanderlodge has a 500 HP 8V92. Turbo + aftercooler + supercharger + 2-cycle , and it was still gutless. We almost got stuck at a high elevation campground because the RV simply would not move up the hill in 1st gear. Had to back way up and make a run for it to crest the hill at walking speed. There may have been some options to increase power , but then one day it would not spin over. Come to find out the engine filled with water through the exhaust stack. So I bought another 8V92 out of an identical Wanderlodge, drop in replacement. Then I thought well do I want to do all this work and still creepy crawl up the hill? I thought of a Cat 3406 which is a wonderful. Then I came across a Cat 3412 , now that's the Cat's meow so to say LOL. It's a 60 degree V so that helps with the width. Ironically the Cat was also waterlogged so I'm currently rebuilding it. Although currently I swapped to building an addition to the house, hopefully will get back to the Wanderlodge in the winter.
That was my debate as well. Do I want to go to all the trouble of a repower for slightly better performance? Being a front engine I was limited by width and height so I spent quite a bit of time at Richie Brothers measuring engines. The M11/ISM was the biggest one that I thought might fit. And also the smallest that comes with a proper engine brake.

We had 3208 in harvesters in the 70s they were tough motors take alot of abuse
I had one in a TR86 it had 10,000 hrs on it
If anyone knows, why would they put the intercooled 3208T's with higher hp in motorhomes instead of trucks that do alot more work?
Single ring pistons, they only last 100,000 miles when turboed
