Is it by chance a 455?

It occurs to me "center kitchn" may not mean the same to all of use. You may be referring to the kitchen behind the entry door.

The Royale center kitchen I am referring to, has the kitchen located on the
curb side of the coach. The kitchen is located to the rear of the entry
door. I'm not sure but I think it's the only '73 to '78 GMC MH with the
kitchen on the curb side of the coach, and I have only found it in
1978 Royale's by Coachman. Therefore they are only 403's and no 455's?
If this is true, will a rebuilt 455 and transmission bolt up the same and
replace the 403 without major modifications?

Sorry for the late reply but it apparently is now moot :). The kitchen in mine looks like a 70s brochure that I have seen when I google image gmc motorhome. Kitchen counter from the back of the drivers seat to the refrigerator which is directly opposite the entry door.

There is nothing unique about the TH425 transmissions. They bolt up to the 403 and 455. The 455 can be installed where a 403 was. The motor mount is the same. However, the accessory brackets won't fit and I would not advise using the 403's right hand exhaust manifold on a 455.

A couple of points:
1. All but one Royale layout had the kitchen behind the drivers seat. None of these was called a "center kitchen."
2. All of the published Royale layouts put the refer across from the entrance door.
3. The true center kitchen has the kitchen just aft of the entrance door... over the curb side rear wheel well. (See link below at the bottom of the page.)
4. Coachman was known to put out one-off models with "normal furnishings" rearranged. So it is possible that almost any layout could show up from any year. BUT... the only year that the published brochures list a center kitchen (Ck layout) is the 1978 brochure: <http://www.bdub.net/publications/1978_GMC_by_Coachman/1978_GMC_Coachman7.htm>
5. As all Ck layout were 1978 (supposedly), they all would have left the factory with 403's. It is possible that a 455 was swapped in. I understand that in late 1977 and 1978, some dealers actually ordered 455's just to make the swap for customers. Removing brand new 403s. (Yes, they just bolt in... with the correct brackets and stuff.) This also means that some came with EL and some with EL2.
6. I also think the Ck was the only _26 foot_ GMC with the kitchen on the curb side. MOST 23 foot coaches also had the kitchen on the curb side. Seems (IIRC) for 23 foot coaches, the side baths had curb side kitchens, rear bath had street side kitchens.

This all begs the question - why the interest in a motor swap? I can say with absolute certainty that a 403 will move a '78 Royale Center Kitchen along very nicely.

It was from a question by Ron Murray. at this was his first post, I suspect he either has just purchased or is thinking about purchasing a 1978 Ck Royale. Like many, he has questions about the "smaller" motor.

Ron,
A little off topic, but...It looks like you have found your GMC (sig line says "77 Eleganza455"). Congratulations! Just a note to let you know the Kingsley you were considering, in Tucson, has been sold after being inspected and found to be in very good condition with only a few minor issues. The new owner will be picking it up today. I hope to meet him.

That was my assumption, too. I remember when I first started looking at GMCs, I was concerned about the horrific loss of power I'd have to endure by buying a late '77 or '78 model with their "tiny" little 403ci motors. Then I did the research and found that there's a whopping 12 horsepower difference between the two, and some other ancillary benefits to the 403. I'll try not to start a 455 vs. 403 war, but suffice it to say that there's really no reason at all to be concerned about having the 403 in your coach. I have PLENTY of power with my "mouse motor", and wouldn't swap it for a 455 if I could do it by snapping my fingers.

We have the 403 with the 3:70 final drive. We tow a cargo trailer with a Harley
plus a bunch of other crap in it with a total weight of approx. 3,000 lbs
including the trailer. Our coach performs fantastic. Plenty of get up and go,
I have to pay attention to keep my top speed down to 70. I'm very happy with
this package.
There are pro's and con's for both engines, bottom line is that both are good
and will do the job well. Whichever one you have, use it and enjoy it.
Oh, and with either one, you'll probably get 8 -10 MPG !! LOL

Ray, & all
Thanks,
I'm curious what is the tac and vacuum readings at 60 mph and 70 mph w/ the
3:70 and how different w/ 3:07? The engine runs at higher rpm's, doesn't it
w/ the 3:70 gear ratio? Is it better to run at 55 mph, 60 mph, 65 mph, or
70 mph?
Lastly why do both the 403 and 455, need to be rebuilt at approximately
100k?
Do any make 200k?
And who rebuilds the best GMC 455 and 403?
How do I make a rebuilt preform well and last for 200k miles?
Ron

Thanks,
I'm curious what is the tac and vacuum readings at 60 mph and 70 mph w/ the
3:70 and how different w/ 3:07? The engine runs at higher rpm's, doesn't it
w/ the 3:70 gear ratio? Is it better to run at 55 mph, 60 mph, 65 mph, or
70 mph?
Lastly why do both the 403 and 455, need to be rebuilt at approximately
100k?
Do any make 200k?
And who rebuilds the best GMC 455 and 403?
How do I make a rebuilt preform well and last for 200k miles?

The vacuum depends on the altitude, the terrain, and the weight (including what you're towing). I've seen my 403 pulling anywhere from 4 to 18 inches between 60 and 70mph, depending on the altitude.
Yes, higher numerical ratios in the "rear end" mean the engine turns faster. I have 3.42 gearing.
It's better to go slower for gas mileage and wear and tear on the engine (see a related thread that's currently going on now on the difference in gas mileage at various speeds).
The motor in ANY 12,000 pound vehicle is going to be stressed "just driving along", and will likely need to be gone over at around 100,000 miles (though some obviously do go farther between rebuilds). I haven't had enough experience to say who does the best rebuilds, though I know my recent (5,000 miles ago) rebuild at MGM GMC - done by the PO - has been done right, apparently. I've heard rumors that the 403s generally don't normally require a "full rebuild", but again, I haven't had mine long enough to find out.
I doubt many of the motors will be driven 200,000 miles before needing work, though it is probably possible with careful maintenance, frequent high-quality oil changes, and a very carefully placed right foot (maybe a 55mph max?).
Oh, here's a WEALTH of information on the subject (403 vs. 455 and rebuilding options): http://gmcmotorhome.info/engine.html#403_VS_455
