Both are about equal up to abround 2000hp, then the crank in the 3408 comes back into play as the weak point, for stupid horsepower it would be the KT.

If I were blowing money to build a big cube motor, I would pass on both and start with a C18.:thumbsup

Got to stick with the yellow paint.

 

[SmokinCAT]

If it was inline and mechanical............QSK19

If it was a V-8..............MACK

The 3408 can't be built to make the power of the two listed above. I've seen strong 3406E's kick the snout out of very highly modified 3408

Greg Hibbitts has the only 3408 I've seen that ran good..........$175K good

That price is comparable to what is in the motor in "Killer" according to JR Collins, but the end result is the major difference, I didnt see Hibbit's truck run that good too often.

I take it you dont like barnetts setup in his KW.

They all have there limits, and with the big motors all the part are expensive and hard to get, both will do all you want to do on the road, it jsut comes down to a matter of preference.:sofa:

Barnett has done an unbelievable amount of modifying to get where he's at. He uses the pump off the MACK. He's also broke alot of parts over the years. He's been beaten by a 1LW 3406E recently and I don't think there is anything left for him to do to it without spending a tremendous amount of money.

Thanks for the info, I knew he had dine quit a bit to it, and I always wondered what he had done to get it to hold together for this long.

I know it kinda doesn't pertain to this thread, but does any one follow the NTPA semis, those 2 walker trucks have been giving KTs and the V8 macks fits all year with their poor little 3406s.

 

[SmokinCAT]

Doesn't one of their trucks have a 6cyl also?

At one point in time they were running 3 trucks, one with a 3406B, one with a 15.8L/C16 converted to mechanical, and the Peterbilt with the 3408 in it. :thumbsup

 

[SmokinCAT]

Crane place next to my work has 2 Petes with 3408's and 6x4's. I drove one around the block and it felt like a Camaro!

Unfortunatly they cant use them anymore here in Ca and they are against the gate with for sale signs on them

Prices?

 

[SmokinCAT]

I think that C16 is one I got a pic from a forum with the belt driven sigma? Totally a work of art. I just can't imagine how anyone can justify spending that kind of cash for something that will NEVER pay for itself. I'm all for having fun but......Talking to Mark at CDS and him talking about the tractor guys blowing up $10k turbos and dropping another 10k without even thinking about it is way out of my league:throwup. He said the semis are spending more because the go fast parts are more scarce.

Yep, and the guys selling them know that and can charge what ever they want.

I priced some stuff from cyclone a while back, Im glad I was sitting down. :bang

I,m loving the reminiscing,. i had a 3408 in a 79 pete, rack was twisted in it,.had a 15 over with a 4 speed brownie,.
("60 speed" i used to tell the yankees,.) but it had stiff competion with the big kta's,.. a company called porter had some brokers with k100's that used to run 'em hauling 'a' boxes here in canada,.
i,m a little confused tho,. i,d like to know the math on the gearing and rpm to run 130 mph,..
even 100mph is pretty good,. i had another pete a few years later with a b model and it had an 8 speed with 3:90's and big rubber,..
the k100 i had had a 12v71,. it had n80's in it and had a bhasterdized 13 double over, and was fast and mean sounding with an empty flatdeck
Funny how trucks get stronger and faster as the drivers get older,..

Nick

According to my math, if you were running tall 24.5 rubber with 3.55 rears and had a .62 overdrive you would have to be turning 2200 rpm and that would get you about 132mph.:thumbsup

With todays 3.36s and 3.23s it is a little more realistic.

 

[SmokinCAT]

I wanna see the day you turn that thing into a sled puller and go after Dave Greek and all them guys to see what a hot caterpillar will do against them guys.

I know I have seen barnetts truck give them a run for their money on the right track, but I think your truck would surprise them. I know the KT we pull with is the best running mechanical truck we pull with, but the guy with the very hot E model makes us look stupid.

 

[SmokinCAT]

The reason I was saying that is because the guy who said cat get owned has two big cams and he is in no position to say that considering a big cam is probably the biggest pos i have ever owned. I love how yall think the KTA is great greatest thing ever. Cat built the world while cummins built the anchors to hold it down!

Pretty harsh words against one of the most reliable motors built up until cummins screwed it up with STC, for the people still running mechanical motors they are a good option for cheap parts and good fuel mileage.

As Haney said you havent been around too many KTs, or your opinion would be different, they are in a class of their own these days, to me they are built more in the mind of a caterpillar, they are extremely overbuilt for a stock application.

Then there is the old saying there is no replacment for displacement.

 

[SmokinCAT]

Well my dads friend has a 2001 KW KTA-600 (more like 850) and he was pulling a lowboy and on a hill he passed a greyhound bus. The people on the bus were shocked to see a semi truck up shifting gears (10+4 transmission) on a hill, AND passing a greyhound bus with a lowboy.

Unless he did alot of work it's not a KT in a 2001 model truck. They haven been put in trucks since the early 80s same thing on the 3408.

 

[SmokinCAT]

Well I had a 1982 International 4300 with a 400 BC and I never touched it besides change the oil and it blew up with 250 K it was just a local produce delievery truck. Then I also had a 1984 International Eagle 4300 with another 400 BC and it did good it made it for 300 K. Once again never put a button or anything in them and they blew up.

Still don't see the correlation between them and white trash, and your above post isn't really a reason, it just shows you can't keep a motor together.

 

[SmokinCAT]

I like how all of yall put these two in a battle with each other at a sled pull where it has to stay together for 300ft. These motors were intended to burn up the asphalt! I have used them in REAL applications not vocational. I had a turned up 1693 that whooped a many of KTA's on the grapevine, donner, cabbage, vail, ranger you name it! The only things I couldnt hang with was a 3408 just an amazing motor. SS got a ticket for 128 MPH in one in Arizona and he had the fastest trucks on the road. Every guy a ran with back them that had a KTA little snake doctor always had problems with his i believe he said it would overheat and it had camshaft problems too. I know yall dont care about actual trucking applications all yall care about is 300 ft.

What was the gearing in the truck you got the speeding ticket in. I don't believe Lenny mentioned anything about sled pulling.

If your so in love with these dinosaurs why aren't you still running one, please enlighten me.

 

[SmokinCAT]

My truck is tooooooo loooooooong for the sled. I'd need to cut 50" from the wheelbase to be competitive with who you're talking about. The E model.........is it a lil black Pete daycab? If so, I have a LOT of knowledge as to what's done under the hood of it..........

Nope, its not that truck, we are a little to far west for any of them guys, I think I know who your talking about though, fox trucking right?

It would be this one; http://s293.photobucket.com/albums/...mm65/Truckinbobb/Preble County Smoke Out 2010/?action=view&current=M2U00392.mp4

Personally I think you would fit right in with some of them large cars they use for pulling. oke

 

[SmokinCAT]

All a 1693 needs is a good stinger and bye bye to everything else on the road.
Nothing sounds like a 1693 when it idles it sounds like a million ballpin hammers randomly hitting each other. Once you got going it was a actually one of the more quieter engine, man what a turbo whistle they had! The harder you worked them the better they like it. Had to be careful pulling big hills if you werent careful you would wear the drive tires down because it had that much torque. The main problem with the 1693 is it was heavy it was back in the by spliy tire days and it was nearly impossible to keep steer tires on it. These motors lasted forever!

Man it just keeps getting deeper in here, a stinger? We aren't talking about an 855, 1693s actually had screws, and needed to be tuned similar to an 3406A. It's been proven on here a long time ago that they don't really make that much power with what the guys were doing to them back in the day, maybe 540hp to the wheels at the most, and that number came from the only person I have ever heard talk about cutting the cam drive quill and advancing the top end to gain some more.

And wearing out tires on long pulls, just chalk that up to junk tires as well, they don't make as much torque as a the newer 3406E/C15 and you don't see guys burning the tires up on them.

 

[SmokinCAT]

That truck runs good, but could use some rpm.

fox trucking..............hmmmmmmm.

That truck should be even more interesting to watch in the future.

My truck.........I got so tired of changing clutches one year trying to find something to hold to the motor that I refuse to hook it to the sled to hurt it.

I have mentioned boost engineering to him a couple times, but he didn't seem to interested, the main problem he has is that he doesn't have a stroung enough clutch to be able to get off the line in the gear he really has the power for. He did say that a new one was going in this winter though.

I honestly think it could use some more air, but it's not mine.

I understand about clutches, I was pretty hard on mine this year, I couldn't imagine what it would be like at your power levels, I'm still looking for an electronic motor to start playing with, but haven't had any luck yet, with the normal trucks we pull with it won't take but a good tune and a set of injectors to compete, and I think an electronic cat is the only way to go at this point. :thumbsup

 

[SmokinCAT]

Hey, a 109R-A1 Vtwin has 4.5 bore two cylinder gas bike motor. The biggest production piston on highway gas in the US today oh look, a bunny rabbit :happydance oke (so could not resist that ya know )

LOL, you sure you took the right medicine today? oke

 

[SmokinCAT]

If you're going after this guy with a CAT, you better pack a lunch....

I agree completely, after seeing the luck both Barnett and cliff lick have had trying to do so, I believe that the only feasable way to try and compete is with a very built 3406E/C15-16. It seems to me that the mechanical cats are too tempermental at high HP levels.

Welcome to the garage as well, when ya get a chance check out the truck pulling thread.:happymugs

 

[SmokinCAT]

Dont do any pulling but am currently trying to find a 1MM crank to convert a 2WS. Couple of big cats in area(5DS,7CZ), tough to beat...:bang
Dont want to beat them, but want to stay with 'em and make them wonder how much more i have... Hard to beat cubic inches. :happymugs

Yes it is, and considering that even with a 15.8L cat your still giving up almost 200cid to a K series its not even funny.

I think you would be okay with your 2WS, you can make an equal amount of HP, you will just be giving up a little torque.
