440-WOB Part 2 - Continued...
« on: August 28, 2008, 02:46:07 PM »

I have a chance to pick up a '73 440/727 out of a Winnebago.
It (supposedly) has 80k on it and was running when it was pulled.
I'm not too concerned about the abuse it got lugging around a Winnie because I want to rebuild the motor and tranny for "The Nyb".
 
I know there were minor differences from passenger car engines and trannies, but, I can't find any specifics.  I'd like to know what I'm getting into before I spend the money. I know the differences are no biggy.  I just want to know what they are.  Since it will be a rebuild, I'm not concerned about it being a low hp engine.
 
BTW, I think for 400 bucks, it's a good deal (as long as the motor spins).

Motorhome heads had extra water jackets in them.They can be used in cars no problems.Just be carefull in selecting head gaskets and mind the dremel if there is any porting planned .
Double check the lower rad hose outlet on the water pump housing.Some are on the right and others may be on the left.
Re-use the NYB one if you have to.
The motor is a drop in deal-no problem.Just use the C body motor mounts on the block.
Passenger 727's had only three front planetary gears.

The RV transmissions have four front planetery gears like a Hemi 727--that is good.
However, depending on the RV manufacturer's specs,most have a short tailstock and hanger bearing  for the two piece drive shaft.--That can be bad.
Why?
 Most cars like the big C's had long tailstock shafts and one driveshaft assembly.
The tranny will work but will need some pawtz swapping in order to work--- should it be a shorty tailstock jobby..
Be sure to use the car exhaust logs not the center dump RV ones.
You can E bay the center dumps since they fit most trucks that are  equipped or converted to B/RB engines.From the Sweptlines of the 60's all  the way up to 1993 trucks..
For the $400.00 bux it is a good deal and can work in the NYB with minor fuss.. 
Hope this helps.

Stan, I don;t know about the 440s, but the 413 MH motors also used a different water pump housing and exhaust manifolds.  These can all be swapped for standard units as the blocks are the same.
 
The use on such a motor, even at 80,000 miles is not bad.  It would never had been raced, and probably never went above 70 MPH.
 
I'd say you made a good find.

Also the RV engines have a slightly bigger cam. BONUS!!!!
 
I just heard at a local cruise -in that  the center dump exhaust manifolds command big bucks on E-Bay because the guys that have or want to put a 440 in a pick-up can't find em. I guess they are getting scarse maybe you can get the 400.00 back in the manifolds alone!!
Good luck!!!

Good to know but kinda a moot point.
I have learned to expect the worse and would do all new internals.
400 bucks from an unknown redneck out in the boonies? C'mon, now......

Instead of gutting a C for it's heart, gut a gas guzzling Mo Home
 
I have a 77 which had the E Brake on the tail shaft of the trans.  That is in a 700 chassis.  Someday, I am going to go up there and drop it out the bottom and bring it home.  Only has 34,000 on it too

I just ran across a tidbit that the MH blocks are stronger because of a higher nickel content.
 
T or F?

1973 ws the last year for the desirable forged crank and the nickel content in the block was increased.
Later blocks say,76 to 78 have the highest nickle content.
Regardless,any machining should the block require will do fine whether if you are boring it out ,or making a killer stroker motor.
The RV cams are one step up from lo-po stock but are down from the TNT/Super Commando/Magnum cam.With a 260/260 duration it has a good torque band,smooth idle and still hauls a$$.I have it in my Barge.
Just ask any of the Mob who rode in my car !!LOL!!

Well I dragged that suckah home today.  While pulling it off the truck in my driveway, the engine flipped over upside down because of my carelessness in chaining it up.
It puked all its internal precious bodily fluids out onto the driveway.  So, there I am, in my deed-restricted community (read: working on vehicles prohibitted   ) with an engine lieing on the ground and a hazmat mother lode pouring down the driveway into the street.
 

 
I had just enough speedi-dri to contain the ecological disaster.  Off to AutoZone Mon. morn for another few bags.

Find a Club Cab truck guy who has a car tranny and see if he is willing to swap.
Just an idea.......

Actually, I think I'll just try to sell it or trade it for something I need.  The MH block had headers on it which I declined to take so I could use a cupla logs.  Tranny for logs. Hmm...

Right now my thoughts are to build a Torque Monster that would get 25 mpg and put that into The Nyb.

And YES!!! I'm interested in the logs.  Lemme grab the parts book and see if they're the same...
