78 440 engine horsepower rating	joe from nj	12-31-05
I have the chance to buy a 440 engine from a 1978 dodge motor home can anyone tell me the horsepower rating of this engine and what was the last year of production of this engine and is this engine internally balanced or externally balanced thanks again joe nj
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. Warren

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!!

I have a 1979 C-Class Dodge motorhome with a 440-3 what is the difference between thia and a 440
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	Steven Smith	1-1-06
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	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
76 440-3 compression psi	Fred Amor	11-9-08
I would like to know what a compression test should show in a 1976 440-3 engine that has 90,000 miles on it. Thanks Fred
Re: 78 440 engine horsepower rating	Frank	5-15-07
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.

What is the firing order on the 78 dodge 440 engine
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	pb	8-22-08
I have the opp. to buy a 73 440 that runs and is still in the original 73 champion. i would like to know if these engines are for a high perfrmance app. I intended on putting it in my 69 dr coronet
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?
