Building a 77 Monaco Wagon, I got with no motor or tranny. VIN says a 400 motor came out of it. I have a 440 with tranny out of a '78 New Yorker that I built headers for installed a mini starter only to find that it is not going to drop in like I thought/hoped. I was expecting a drive shaft length adjustment. Oil Pan not clearing Cross member. Tranny mounts not going to line up with cross member. Header hit brake booster (my bad there and fixable) Headers (any 40 exhaust manifold?) also look like they are not going to work with Steering box. I did alot of work to motor and car in anticipation of them combining relatively easily. This looks not to be the case. This is my first ever motor swap, because I always feared this and I am not a big mechanic. Luckily I do have a shop, welder, torch, so there is some hope....lol Is there any tricks to make this motor fit? Is it feasible or do I need to move on? I have an '80 3/4 ton regular cab Chevy 4x4 truck with a 350 in it. It was bought to derby, but truck derbies have not taken off here yet. Would it be easier for me to fab that motor in vice the 440 motor? I am sure that requires motor and tranny mount fab as well the drive shaft adjustment. Any help appreciated~ signed~ In over head Derby6

If your 440 is out of a shocker New Yorker it should go right in a Monaco wagon if it really has a 400 in it. Something is wrong somewhere

I hope your right and I am just that stupid, but it just don't seem to be fitting. If your right, it would make my day. Brake booster and tranny cross member mount would be a pain but I could likely work out. Steering box and oil pan/crossmember meeting up I think exceeds my ability and knowledge base.

i guess it could be a pinch frame car tho...Is the wagon a subframe shocker or a k member pinch frame car. and all chryslers pretty much need forward offset headers for stock brake booster applications.

Yea stromi, dm440c may be my guy here. Fordpowerforever, my ignorance shines thru. I don't know the difference. I'm guessing pinch frame as I'm not visualizing a "k" but 4 body bolts mount a sub frame "H" to the uni body.

do you remember if it had stacked square headlights or hideaway headlights?

Oh yeah, thats a pincher.
The 4 stacked headlights are a dead giveaway of a "Roscoe".
The "H" frame you're referring to is what most of us call a "K" frame.

You need to find a b body or bigblock Cordoba oil pan and pickup,a shocker oil pan is different.This will clear the steering linkage.

Monaco-pinch frame B body car. Lots of differences. Im not sure Ive ever seen one of those factory BB? Royal Monaco-C body. should go right together. Hemi1 is correct about the BB Cordoba pan if youre working w/ a B body car

Read thru alot and didn't see my issue/question. But that many pages I could have easily missed something. Guess I'll try and find a big Block Cordoba oil pan. Its only money. If the oil pan works is that steering box going to clear? Another buddy told me a 400 is longer and narrower than a 440, so that is why the steering box may be an issue.

A 361 to a 426 hemi is all the same length.This is why you can swap crankshaft between them.Anyplace a bigblock was factory you can bolt another bigblock in its place.They did make B body pinch frame cars/wagons with bigblocks in them but majority of them were smallblocks from factory.One thing I have learned the hard way thru the years with mopar cars/wagons it seams there is a different specific oil pan for every body model.example A,B,C body.

I am headed out to play around and possibly delete Brake booster to solve that issue. Call me crazy,but I am thinking about notching cross-member to allow for oil pan to fit. Will just reinforce it on the front side...

TONS of Cordobas made with a 400, I've had more big block than small. Only difference on the outside between a 400 and a 440 block is the 5/8" taller deck. Motor mounts, trans mount, oil pan, heads, all that stuff is the same. The 60's valve covers were a little taller on the ends than the 70's ones, the later ones tapered in at the end. Yeah the B body cars are fussy about the oil pan but between that and the valve covers it's just a matter of having the right ones and it really should fall together, they put 440s in those cars factory (Roscoe police cars!). Bottom line is the swap is completely do-able but you got a bad mix of parts, same for the headers. With the right parts it's a snap, no mods necessary.
