Were looking at a 93 Ford 9000 with a 3306, 9 speed, probably 40k rears, etc. Does the 3306 have the reliabilty and the renowned power as the 3406b cats. Im guessing it does, but Ive been wrong before.

Also is it possible for the 3306 to have a jake head? or is it to small (at 10.3L or 10.5 L I think)

3306 is 10.5 L displacement and the 3406 is 14.6 L so theres no way the 33 is going to match the 34's power.. I work on alot of marine gen sets powered with 33 series cats, great engines and easy to work on.

No not nearly as much power but I think they are more durable then a 3406 personally but your only looking at maybe 270ish hp.

BlueDually

I know there is a 4.1L difference in displacement, and they arent going to match the hp/torque, but for there size there a strong engine?

Is 270 the max hp on a otr 3306 truck engine? How bout the jake, possible on a 10.5L?

Kman9090

Well maybe not a truck engine but I know on our scrapers at work they are in the upper 270's.

In my opinion a 3306 is a great engine. Worked on them at Cat when I was there and they would have mega amounts of hours on them and we'd put in 6 liner kits, gaskets, clean up the head and send it back out.

As far as power goes I'm betting if you find yourself an older mechanic who knows his Cat fuel systems he could tweak some power out of that engine. We had a guy who was in his 60's or 70's and he could tweak those 3406 fuel systems and get them to roll on.

Basically, you won't go wrong with the 3306, it's kinda like the old 350 chevy's and the 300 inline 6 cylinder ford, engines so good they had to get rid of them.

We have a 3306 in this :




It's rated at 300 hp.

3306 is a most excellent engine as is the 3406, smaller and lighter. 2 different engines, kind of like a Cummins C compared to a NTA 855.

Yes possible for the 3306 to have a Jake brake.

Now if you have the room and need the power, see about a Cat 3408 or a 3412. I've seen the 3408 in trucks before, they really make power and get down the road.

How about a Cummins K 19? Now that's a serious engine, in use in some large specialty trucks, gensets, tub grinders, boats, heavy equipment. 19 liters, can make an easy 1000 hp at 2400 rpm without straining. Not sure aht you'd need for a power train but that is one serious engine. Pricey, you won't find one in a bone yard unless it is junk.
I've worked for Cat and Cummins but if I get cut, I'd probably bleed Cummins blue.

Can't put a Jake on a 3306. You can put an exhaust brake though.
The brake specific fuel consumption is not as good for the 3306 as it is for the 3406. Both are great engines but the 3306 had a 2 valve per cyl. design while the 3406 is 4valves per cyl. The 3306 was dropped because it would have to be totally redesigned to meet emissions. Earlier 3306's were equipped with precombustion chambers and the later ones were direct injected. I would also tend to stay away from those that were equipped with the sleeve metering fuel systems and go with the latest ones with the left hand scroll fuel system. I love my Cummins but if I was to cut myself I would bleed yellow.

turns out this little 3306 has a lot of jam, enough for a empty tandem grain truck. Going load it with roughly 17 ton of canola tomorrow. We'll see how much snort it has then

It has 12 000 hours on a rebuild, (sleeves, gaskets, etc.) something like 20 000 hours all together. Seems like a lot of hours for the bottom end though? I think it was originally set a 270 hp, and was bumped up to 305, after the rebuild.

Burns nice and clean, no blue+very little white after idling for a minute after startup. Just a little black when at full throttle. And it has a jake. Also a 13 speed, and 44k rears, 14 k front, 4-way lockup etc, rubber at 60%, it was originaly a oilfield water truck, so heavy spec'd all over.

The guy selling it, is a hd mechanic and has done most of the work on the truck since new, and a neighbour so we are taking his word on the mechanical work.

Gunny, I know a 3408 is a v8, but are the 3412/k19's v8s? We defianetly have no need for that much power anyway, but would love to see one of each. Drove a turbo'd and a natural 3208, v8s. Both huge pos's I thought

The next truck I want, someday, is a 90-94, 379 Pete flattop sleeper with 425, 3406b cat, 18 speed, 46s etc, straight 7" stacks

3412 is exactly what it says a V12. the last numbers means how many cyclinders it has 3406 inline 6, 3408 V8, 3412 V12. They still make 3306 motors but they are for the heavy equipment market.

The 3300 Cat is a bulletproof engine. As others have said, its hard to compare it to the 3400 due to displacement differences. But, the engine is built VERY well, very durable in design and all it needs is simple maintenance. To my knowledge, the 3300 diesel is no more. Its been replaced by the C-7 and C-9 engines... depending on application. The only 330 engine in current production is the natural gas engine. AND, unlike the 3400, the 3300 is just as durable in the N.G. version as it is in the diesel version.
