I have a 1978 440-4 from a truck...the engine assembly stamp next to the water pump housing says 1979, it's rated at 225 hp at 4200 rpm (chiltons) I just put it in a coronet, haven't started it yet, it uses the "452 heads" any info on this late 440 would be appreciated, I never see anybody with 440-4 blocks...always -1 or -3.
Chrysler Cobra casa grande 1978 R.V. steve Richardson 2-24-07  
I have a 1978 chrysler cobra 36 foot RV. Imported into the United kingdom in 1995.

Does anyone know anything about these vehicles as I have scoured the web and can't find anything about it.

This one has been converted to diesel with a 6litre Perkins engine and 4 speed manual box. Any ideas what the original engine was?

It needs a whole new set of brake units but I can't even find what type os chassis she was built on.
Any help or pointers to someone who may know would be appreciated. Chrysler have no ideas!!

Re: 78 440 engine horsepower rating Warren Godfrey 3-13-06  
As explained to me by an old Chrysler mechanic. One of the differences you will find between the 440-3 and the 440 used in street cars, is a longer coolant path between the heads and the block. This is accomplished by including an extra pass from the block up thru the head and back down thru the block again. Since the heads from the 440 do not have this path in the head, using them on the 440-3 is the same as plugging them off..The resultant overheating situation will destroy the engine in short order. Although they are rare, I have also been told that heads from the 413 engine may be used as a direct replacement for those of the 440-3.
Hope this is helpful.

I think 78-79 was the last yr of production for the 440, though some ended up in class Cs up through 81-82.
The HP figures he shows, keep in mind they are the net figures that they went to when all the smog engines started to appear. I think all BB after 71 were externally balanced.
Yours definitaly is.
Re: 78 440 engine horsepower rating rich 12-31-05  
My book lists the 77-78 at 195hp at 3600rpm.73-76 at235 at 4000. I'm not sure what all they changed in those years. I do know the valve lift wasn't as high on the newer engines, they were changing over to unleaded at that time. Rich
Re: 78 440 engine horsepower rating brent vendsel 1-8-06  
The low power in the late 440's comes from mostly very low compression. like 7.5 to 1. the late RB mopar has the heaviest rod and piston weight of any modern overhead valve carbuerated engine. a 1969 440 magnum (or commando)made 375 gross hp, with the same rods and a steel crank. simply because it had a far more favorable compression ratio (the piston wasn't down in the hole at tdc) and a camshaft that was matched to that ratio (around 10:1) 440's make a ton of torque, and there is alot of stuff out there today (keith black hyperuetectic pistons, racer brown custom camshafts fbo ignition systems etc) that let you tailor a 440's torque and hp to where you need it. i've owned 2 440's and 2 383's, if you don't exeed their built in limits (overheating, overrevving) you can't lose. unlike a big block chevy you don't need to carry around spare exhaust manifolds lol

Re: 78 440 engine horsepower rating sean 12-1-09  
The main reason for the difference in hp ratings between the 73-76 and 77-78 is smog. Before 77, the smog was much more relaxed, but in 77 engines were getting more smog controling parts. This GREATLY reduces hp and tourqe. If you look back even further to 70, you'll notice an even greater difference in hp and tourqe numbers. This is again due greatly to tighter smog restrictions. It all has to do with letting the engine breathe freely. More parts for emmisions control, the greater the restriction of the flow of air in and out of the engine.

I also have a question. My 78 Dodge adventurer 4x4 is haveing problems with fuel delivery and has been having electronic ignition problems. The carb's fuel pump simply will not pick up any fuel from the tank. It's got the stock 4 barrel carb on it, so I figured the fuel pump in the carb must be bad. Do you have any ideas? I dread having to rebuild the carb, but I can do it if necissary.

The electronic ignition seems to be putting out a rather eratic spark. I've installed electronic ignitions on fords that had points previously so I know that the spark should be consistant and real strong. My wires are still in great condidtion, and when the truck runs, it runs real strong and healthy. But when it does this, it simply won't run. Do you think it's possibly the control module?

Re: 78 440 engine horsepower rating Jim Watkins 9-22-11  
I have a 77' Powerwagon with a 440 out of a 77' motorhome.The previous owner built this truck for pulling sleds at truck shows. My question is- when he built the motor he used 516 close chambered heads and so far there are no cooling problems, but it is expensive to drive cause it needs 91+ octane and lead additive- can you suggest a good replacement head that will allow me to run 87 octane but still have some performance ? Any help is greatly appreciated, thanks, -Jim

Re: 78 440 engine horsepower rating Kirk Swanson 3-22-08  
I have a 1978 27' Honey class c motorhome with the 440-1 engine. I know they sucked the life out of these engines by the time the late seventies hit. I installed hedman headers and designed a cold air intake for it. Also added a gear vendors over/under overdrive to the 3 speed 727 trans. I can climb the hills at a comfortable speed in the rocky mountains and the temp stays nice even on the hot days. I find it to be a great combination.
Re: 78 440 engine horsepower rating Geoffrey Hammell 10-6-08  
Have searched far and wide. What is the difference between a 440-4 and a regular 440? Can a 440 from a 1 ton van be used in place of the 440-4?

Re: 78 440 engine horsepower rating tony 11-15-10  
The big block trans will bolt up to your np205 as long as it is the short tailshaft all u have to do is remove the tailshaft housing and use the housing on front of the transfer case to bolt to the back of the trans.but i suspect the rv trans is the long tailshaft in this case you will have to disassemble the trans and swap the tailshaft out for one with the correct legth. did the same conversion to my my truck,best thing i ever did. any other question just email me
