The Cummins IS a typical in-line six, in that it fires every 120 degrees. If it didn't, it would vibrate and shake and wouldn't idle worth a crap.

Where do you get the idea that it fires "..3 ALMOST at once..."???

Have you ever seen the inside on any engine?

As for the V8 comment, just general additional info, something you seem short of.

 

3 almost at once,that would mean that for all practical purposes,it would require a rather unusual crankshaft design to do this,plus with nearly half the rotating assembly at nearly top of the stroke at one time,i cant imagine it would be very smooth. Of course this bit of wisdom and science came from someone who actually likes the chevy 400 small block,so credibility is an issue here! You want a torquey truck engine,consider an IH 392,or a GMC 351 V6 these were both truck engines only,no question about there original application. the strongest engine ive owned running gas was a late 60's 428 in a 1972 F100 4x4,even with too tall 3.50 gears and 35" tires,it had power galore........running oil,im very satisfied with my 07 Dodge! I bought it for its engine,plain and simple......I liked the Super-Duty,had it been available with a 5.9 Cummins and an Allison a/t,that would have been the perfect truck.

 

And I thought I was the only one who doesn't like the small block 400 chev. I am definitely no Chevy fanboy, and I will give credit that I think the small block is a decent engine, other than the stock 400. If i had to have a Chevy engine in that size range I'd rather have a 396.

 

uh yea.. the 400 small block chvey was one of the WORST small blocks. You can tell 6.6liter knows little in the design, casting, and workings of an engine... 400cid chevys were RE-CAST with siamesed cylinders, to allow a 4.125 bore. BUT, they didn't relocate the cylinder head bolt locations, to use sbc heads. Sometimes, oil consumption in a chevy sb 400 is caused because some of the head bolts were torqued incorrectly, causing the nearest cylinder to WARP!!!! Many assumed the oil consumption was due to badly seated rings, etc. The head bolts were too close to the cylinders, and the lowered cooling ability for the cylinders from the siamesed design turned a torque error a big problem. (my source: Chevy Small Block V-8, 50 years of high performance, pg-83).

The 400 chevy was known as Chevy's "400-inch Bust." How was the 400cid chevy comparable to the 460 Ford again???

6.6liter, i was a Chevy man way before i bacame a Ford guy (the 327 is my favorite engine). I like them both now, any brand will last if maintained. You just don't know what you are talking about.

Im going to guess that 6.6liter troll will likely just slink back to his corner like a whipped animal to lick his wounds....... he quite obviously knows nothing about Ford's, Chevy's or even the basics of internal combustion engines........ I guess it could have been worse,he could have named himself after the GM 5.7 liter diesel......

 

After all these years I finally know what it stands for.I always thought it meant Cracked Heads Every Valve Rattles Oil Leaks Every Time..

 

What do you Chevy guys say to this? I understand this guy specializes in 385 series Fords but still.

460s are a very tough motor that will take abuse. In truck competitions sled pulls,mud bogs an mud drags the 460 shines. In all the years Ive watched truck pull an competitions I havent seen a 460 blow up yet. Did see one where the rod bearing went out an it ran with knock for 5 years that way. It refused to die. Ive got a couple off 460s I use in industrial use. Under hard loads an many thousands off hours off very hard use. These motors havent let me down yet. One is twenty years old with thousands off hours. I am huge 460 fan an always will be.

 

I have a very good friend who competes in the engine masters competition. He probably has a bow tie branded on. The last time he went they had revised the requirements to favor torque in addition to top end power. He and his son both grenaded their 454s as the requirement for the low end power made him play with the timing and burned pistons. He did say the 460 Ford that beat him was pretty much stock. My own 86 460 will spin all 4 rear tires with a 3:55 gear.
There was a fellow around who had an SS454 Chevy truck, my 77 with a camper special 390 would walk all over it and get 16 mpg on the highway. I'll stick with the 460 even with the poor exhaust port design.

 

like i said i re-built the engine and while i was at it i torqed the bolts properly.....the 327 is decent.....dads 01 chevy has 1 and right now my uncle is fixing a dodge 318 even better cause u can wrap the hell out of them i dont know if its your experiences with 400's but take my word for it the one i have has never had any problems other than using a lil bit of oil an the carb has been messed up for awhile other than that its all good.....maybe i got a good one compared to what uve seen or heard? but in my personal experience this is the best engine ive ever used for a gaser ...the 460 isnt enough and niether is the 454 not to get off topic real quick but i am about to get my hands on a 440 how do they compare to the 454 and 460 never delt with mopar other then the 318

 

I can imagine some emissions issues with a 327 in a 2001 vehicle.....Wasnt the 327 discontinued around 1970 or so? Or maybe you are in area with relaxed emissions standards

 

no duh itll spin them its 3:55 for gods sakes.....but my 400 is on the sierra grande all time 4wd and it spins them with mud diggers on and hell yes i know what the hell a engine looks like and i know how it works i wouldnt be here if i didnt and a cummin mechanic himself explained to me how it works and thats exactly what he told me it does have a oddball crank and is a multivavle pushrod system

althoguh the way most of you talk you use these engines for stuff such as races drags and entertanment puposes? except one he said industrial the 460 is ok for pulling but it chuges 1 gallon of fuel uses half of it and spit the other half out the pipes.....anyways thats the case in my buds 460 although in his case he uses it for screwing off and burning rubber sicne we put a new rear end in it he blew the gears out of his old one this one was made for the quarter mile...forgot its ratio but its a posy but when he pulled his 40 ft camper 5th wheel with the new rear end or the odler one the truck sucked for pulling it could barely get speed...although since he has glass packs and 3'' tips it sounded pretty nice echoing against that camper under all that strain ...the best engines for actually pulling stuff though is cummins duramax 454 depending what it is 460 if its light pull and 400 for medium duty stuff...and ill be nice and add the pwoerstroke although itll never live up to the duramax or cummins.....o yees and the 6.5L from the late 90's was a excellent truck....was added to the military humvees

 

scuse me i was thinking old small blocks i ment to say 293...

 

that is where you are wrong my son...the 460 torques at 930-960

 

You wouldnt be here if you didnt know how engines work.......really?
Did the Cummins mechanic try to sell you a bridge,or tell you about those Cummins specific spark plugs?
Spinning mud tires on pavement isnt difficult,not a lot of tread contact with a hard surface road........400 small block and Full-time NP203 t-case,lousy mileage,lots of parts wear,at least GM didnt put the full time behind Manual transmissions for more than one year,or go to the small failure prone wheel bearing design of the 1/2 ton dodges
