I knew it had to be a special power plant with that long nose.
Engine pic's are a must and I wanna see polished air to air charge piping!! LOL!!

BTW, That's one crankshaft design I thought would never work in my younger days. Boy, Did I get that wrong. Caterpillar has showed strong since the early eighties on that engine.

I always heard that back in the day when they first put them in trucks if you turned them up past 550-600hp the crank would break. Even more rare to see a truck with an 1676 cat.

I am not sure, a friend of mine sent that to me. I have a couple buddys running long hood Petes with 3408's, they sound so cool. I hate working on them , all my friends have Brakesavers on there 3408's, B's and E's . Its like working on a 019 top handle.

They can build a Crank and tough bottom end for sure, I used to love loading them down to 1200 rpms's on the dyno full load and they keep pulling. I wish I would have got some pictures of the truck drivers faces, they looked so nervous.

I'm not sure of the 1676?? But back in the day if you got your doors blowed off by a double bunk KW cabover with a distinctive cackle sound it had a Cat 1673 or 1693 engine. 6-cyl, dual overhead cam, pre-combustion style. Heavy, dirty, and poor fuel mileage but excellent torque and horsepower. I'm not being the Cat police here but used to bleed Cat yellow LOL!! Now I bleed the other yellow that starts with a K and I'm not talking Kobelco!!

Yes, I hear ya Ryan. That is the only engine with the offset rod journals on the same throw. The 3412's were a straight journal for paired rods. I guess it was the degree of the vee block used in the 3408's as to why they did what they did to the crank.

Komatsu makes nice stuff. 1693T was a powerhouse and way underrated in it's day. Would pass mostly anything going up a hill, the 1676 was basically the V8 version, also known as the V8 D336. I'd love to have a '72 359 with a 1693 in it, like a bag of rocks idling.

Very good sir. Didn't know that for sure!!

 

[NWWrench]

For all you 3408 and 1693 lovers.

 

[NWWrench]

The cabover has an 08

 

[NWWrench]

The Pete 389 above has a 1693 installed is what I was told, WHY WHY WHY. Lots of money involved right there, I am a engine / truck guys so I do think it is pretty cool.

Ed Olsen:

Very interesting crane. It looks like it was modelled after a railroad crane.

Looking at the truck maybe early 50's?

That 359

352's make the best sleepers. I've heard of people stuffing KTA 600's in them as well
