440 short block

[McGuyver]

Here's a picture of my assembled 440 short block that I am building to put in my M880

Hmmm.....that's a mid/late seventies block, isn't it?

Double roller with flat tops.What cam and heads are you going with?

 

[Elwenil]

Going to stick with an auto trans or going to a NP435?

 

[red devils dude]

WOW me like but I'm more of a diesel fan.

 

[Elwenil]

Diesels are nice but it's hard to match the raw power of a nicelly built big block Mopar. I have a 383 in my Dodge and it will out pull a lot of light diesel engines. MPG is a joke, but what theh hell, lol...

That's what TWO fuel tanks are for, RIGHT?

LOL! Thanks for the replys guys!

Clinto,
yes, this is a `76 440 block, with cylinders milled .030" over, and crank milled .010" over.

Kenny,
You are correct, double roller timing chain, flat top pistons with a compression height of 1.990" (deck clearance of .092"). 452 head castings with .030" milled off yielding a burrette measures 82.3 CC combustion chamber volume. With the .039" Felpro gasket and the above listed heads and pistons I will have a true 9:1 compressioin ratio. Cam has 278 deg intake and 288 deg exhaust (SAE) duration, cam lift of .281" intake, .296 exhaust. Lobe centers at 107 deg intake,117 deg exhaust.
As you pointed out, a big block is not for the fuel economy conscious crowd. But this is not a daily driver, so I can afford to build it as an expensive "toy".

Elwenil,
"heavy duty"( or high performance, I'm not sure which) Loadflite 727 automatic transmission. I'd prefer the NP435, but the 727 is what came with the motor.

RDD,
I like the Diesels too. Particularly the Cummins 12V 5.9 liter intercooled turbo diesel. That is the next project in line after this one. Maybe a swap into the M880 down the road?

wallew,

I actually have another club cad Dodge (`76) with a 440 that has two gas tanks as you said.

sounds cool, I would like to see more as the project progress'

 

[pistolnut]

I'm glad this came up. Yesterday I was offered the powertrain out of an old motorhome. I'm told it is a Dodge 416ci 265hp engine with auto transmission. Runs good, 35K miles. I don't have a project to put this in, but I'll bet the price is pretty right. Should I bite?

 

[McGuyver]

If the price is right, then sure I'd go for it. BTW, I don't think that engine displacement is correct. It sounds like either a 413 or a 440 coming out of a motor home. This page talks a little bit about the 413/426 Heavy Duty RB Truck Block:

I am putting a 413 BB truck motor from a motorhome into my 5 ton mudder. They are suposed to have lots of torque! It is from a 1971 Champion.
what would the HP and torque be? do you know where I could find any more info on it?

 

[McGuyver]

Here's more info than you probably want or even need about the mopar line of small and big block engines:

Here's a discussion group I found discussing the 413 and 440 found in motor homes:
