So the current C7 isn't too bad of a match weight wise. I'll look into what the new C7 is going to be weight wise. It's a 7.1 liter inline 6 coming out of the UK development center. The also have a C 6.6. The 6.6 puts out 175 hp with all the emission systems for the new tier 4 regulations for the off highway engines. The 7.1 puts out a bit more. But that's emissions compliant for off highway regulations that are not even in effect yet, and designed to go 10,000 hours before a rebuild. I'll have to look into the upper limit of their power if you drop the emissions and don't expect 10,000 hours. There is also a C 4.4 which is a inline 4 cylinder, but that tops out around 120 hp in full emissions dress.

This could be a really fun project.

 

No way on the 3408 cat. What they are talking about is a 3208 which is a way smaller engine and could be crammed into a ford SD.

 

I was just kiddin around, when I typed that. I was on youtube earlier listening to a couple of 80s peterbuilts with 3408s in them COOOOL.

 

Dont you mean meoowww???

 

LOL... I was told once that only the Cat Ford service trucks had the cat motor installed in them , and Cat installed them.

 

I have a fleet of Freightliner M2 Business Class trucks equiped with c7's. There is no way you are going to fit one in an SD unless it's on a pallet in the bed. Even if you could make it work, the motor is terribly under powered and extremely bad about constantly breaking down. Even the Cat shop will tell you that this motor is better suited as a paper weight than as a means of moving a vehicle.
We had a guy running around here a few years ago with a detroit stuffed into a 79 Chevy one ton. I never got to speak with him so I don't know what motor, but I do know that he had to remove the inner fenders, and them welded up cab supports to lift the cab about 18 inches higher than stock. The truck looked rediculous because the cab sat up WAY higher than the bed and he welded steps to the fram so that he could get into the truck. I used to know where he lived so maybe I will drive by and try to get a picture if the truck is still around.

 

CAT bought Perkins a few years ago to access smaller engines for their equipment. Perkins has a long history of building engines in the power range we are interested in. Also very good engines. I have run a couple in generator sets that were reliable, fuel-effecient, and long-lived.

I have seen 6-cylinder Perkins engines in older Ford pickups before. They were not turbocharged, but that was back before turbos were common.

 

I have heard that, its a engine specifically designed for the super duty class of trucks

Thank You, the C7 Cat is probably the most useless diesel out there, where i work we have a F650 with the C7 and its useless, the 7.3 powerstroke we have in a F550 will out do it

 

We ran a 354 Perkins on an irrigation well back in the '70 and they were rated around 100 hp continuous. There was also a turbo option for them. I've seen a couple of 70's Ford pickups with 354's in them. One ran an electric fan because of the length of the engine.

Perkins also made a 540 V8 that was used in Massy tractors and combines. They were pretty good engines. The 540 made around 150 hp if I remember correctly. Cant remember if that was with or without a turbo.

 

The Perkins in the 760 combine was turbo, the 750's had no turbo and were in line 6's. both were great engines. I will have to pull the spec. books when I get back to the farm.

 

I wonder if the guy the OP was talking to was referring to a 3208 Cat diesel which is a V-8 configuration. My guess is that would be the only engine that would fit and even that would include major modification.

 

Maybe a 3126 Straight 6, 32 and 34 class engines are too big (length and height), too heavy and under powered for their weight when compared to the 6.0, 7.3, and 6.4

 

I have driven 3126, 3116, and c7 accert powered trucks, and in a word they are "dissapointing". They could barely pull an empty 28ft pup in high gear. A stock 7.3 would probably outpull it. CAT getting out of the on-highway market is a blessing to anyone with a cdl. The c15 I have in the truck I'm driving now spends as much time at the dealer as it does on the road. JUNK!!!

 

Sorry about the noob question here, but if you could get a CAT engine in am F-650/750, then why can they not go into a 350? I understand that the front clip is different, and the front lift hood of the 650 gains a TON of access, but if you do the clip conversion wouldn't you be able to stuff a CAT inside? I know the cabs are the same on the 250-750, and the frame is beefier on the 650 than the SD. Seems like changing the front end would allow the clearance needed with plenty of room. Just curious.
