Hi, we're new owners of a fine vintage 1987 36ft Grandvilla. It appears to be well kept and it's Ford 460 looks pretty clean and ran good on the test drive. I found it was an option when it was built and know large Ford commercial trucks use them..... Anybody that could share their experiences with this vintage and model would be much appreciated. Things like how you found the power, comfort, mountain driving Dos and Don'ts..... Etc.
TIA

Welcome to the forum. You will find a wealth of help and info here. It will help others to help you if in your profile you include information about your coach including the build number.
Here is a link to a wealth of info about our coaches: FORETRAVEL Motorhomes service and Repair Information (http://web.archive.org/web/20191218073242/http://www.beamalarm.com/foretravel-links/foretravel-links.html)
Good luck with it.

I have owned a couple vehicles with the 460 Ford.
I owned a 85 34' Winnebago Elandan. The 460 moved it OK, but in the mountains it struggled and got HOT. Hot means the exhaust manifolds warp and leak. I eventually had them replaced with a Banks Power Pack system with headers. Its a strain on a gas engine to move that much weight. Also the C6 trans is good but at its threshold when moving that much coach.
Your wallet will find its way out of your pocket frequently to pay for gas. You will not see a high mileage 460 and trans in a heavy duty application with out a rebuild or one that needs a rebuild.
The other 460 Ford engine I had was in a Ford E350 Pathfinder Quadravan 4x4. It actually ate up more gas than the Motorhome did. I would always change the subject every time my Wife would ask me what kind of mileage I was getting with the Van.
Yes, fuel mileage is poor and you really have to watch temps on grades. We had a Dodge 440 in a 29 foot SOB that only got about 5 mpg. The key is keeping the engine and transmission cool with aux coolers if necessary and not being in a hurry on the grades. Having the heat exchanger for the transmission in the radiator puts too much load on the cooling system. I kept the heater on with the fan on high on grades.
I eventually put a 7.3 turbo Int/Ford diesel with a Getrag 5 speed in the old coach and that doubled the fuel mileage.

In 1997 we, the family - 2 adults- 2 boys, and 2 Labradors, took a little trip with our one ton 460 Ford van and a 30 foot travel trailer. We drove 7,300 miles in 42 days. The trip average was 7.3 mpg.
Without the trailer the van, as a daily driver, averaged 10 mpg.
I talked with number of people pulling smaller trailers with small block engines at 5 to 6 mpg.
It was a great trip!

Post exterior/interior photos when you can.... we own an 1986 Grand Villa with a 454 Chevy gas motor.. 42,000 original miles. We live in Colorado and have taken the coach over a few of the Continental Divide passes... we watch (2) engine temp gauges, we downshift when we need to keep RPM's high and we move to the right lane and take our time...
Once your out of Colorado... its all downhill from there to anywhere.. LOL
We average 6.5 to 7 mpg on our trips. We do not tow a vehicle, rather we have a motorcycle rack on the back receiver for our Yamaha 750 ( 500 lbs)
We have auxiliary double fans that auto turn on with temp readings and hold steady 195-205 degree operating temps for our big block Chevy truck motor..
After almost 4 years of ownership and thousands of miles on the hwy.. we have replace tires and an alternator...
Good luck.... see you on the road...
Our first Foretravel was a 1987 GV with a Ford 460. Loved that beautiful coach until our first trip that crossed high terrain. On the flatlands, no problem even towing a small Honda. Climbing mountain grades was slow with high engine temps requiring frequent pull overs to cool down. After that first western trip, a new exhaust manifold was required. We then purchased a 2001 GV with a Cummins 8.3liter 250hp engine. As long as you could keep the transmission in lock up, the transmission and engine temps would remain in the normal range and mountain climbing was no problem.
No such model exists - I think either model year or engine rating must be a typo.
If it is the rear engine coach. You should consider top speed around 55. Also like has been said it will not like mountain driving.
I had a 1988 F350 flatbed dump. Used during building our house. Great running truck for my application. Hauled hundreds of loads of tailings out of our basement. Ice cold air conditioning. Great low end torque. Seemed it was always out of fuel never leaving the property. Used for compaction with probably four tons on it. Never did anything but routine maintenance and once had to replace the fuel pressure regulator. Was pumping fuel into the intake. Still ran fine. Lots of fuel, lots of tires. Overloaded and driving over rocks.
Welcome to the forum. Endless amounts of information. Search function is priceless.

My first RV was a 3/4 ton Ford and camper. It had a 360 engine. At first is seemed gutless and so I advanced the timing and
that fixed it. The specs were 6 degrees advanced and I moved it up to 10 to 12 degrees advanced and that made it go. Never had
any trouble with the engine.
Our 1989 Class C had the 460. The exhaust manifold studs stripped out the threads in the SPECIAL!! (Note I emphasize SPECIAL) Ford heads. Fortunately this happened after we traded the C. New owner ended up breaking down and the dealer here had to search the U.S. for replacement heads.
We had a 1988 Winnebago 32' Superchief for 20 years. Built on a '87 John Deere chassis, later became Oshkosh.
Front engine, Ford 460 with 3 speed transmission.
40mph uphill. 6mpg with or without a tailwind. No overheating. Narrow set leaf springs top heavy, narrow tires. Very poor handling, especially with cross winds.
To Chuck & Jeannie,
We owned that coach for 15 years and it had a 250hp Cummins engine. It was a perfect marriage...10mpg towing or not, and completely trouble free.
I saw you had a 1991 GV 250hp - perhaps that's what you meant instead of 2001?
Looking for a Grand Villa (https://www.foreforums.com/index.php?topic=40624.msg404007#msg404007)
Sorry Chuck, super senior moment. You were probably correct. Our coach was a 1991.
I have a couple brand new 460 exhaust manifolds and gaskets if you need them. Also an Edelbrock aluminum intake manifold and Performer 4bbl carb, yours might be fuel injected.
Lon and Cheryl.... Thanks.... I think new manifolds are probably gonna be needed. Im in Palmetto FL, where y'all?
I'm thinking about these shorty block hugger headers..... Any thoughts from the group? Anybody done these on a rear engine 460? Sorry I don't see how to upload pics of an.
There should be plenty of room for full size, long tube headers. Makes more power/TQ and may help the compartment temps if you wrap the top 16 on or so. The Staineless E bay are cheap enough and seem to work fine .
The 460 Ford cast iron exhaust manifolds I mention were for the 460 E350 4x4 quadravan I owned at the time. I had replaced a couple sets of exhaust headers because they always rusted out( Doug Thorley brand as I remember). I was sick of replacing them so I bought the new cast iron manifolds. I got rid of the Van before I replaced the headers for a 3rd time.
The headers (part of Banks Power Pack)that were put on the Winnabago Elanden 460, worked great. I did not have the coach long enough to see how long they would last.
Thanks for all the insight, guys. I've gotten 19 of the 20 bolts in the headers and flanges broken loose and ready to come apart.... There's always that one!!! Workin on it w wd40..... Hate to have to cut it and drill/tap that one hole..... I'll keep y'all posted
Hey guys..... Just finished our first campout with the rig..... Everything went well except that I failed to assure that we had all the correct sewer fittings for dumping...... Alas.... I'd overlooked the crucial coach connection.... The hose and fittings I got w the unit was all one size too small for the coach connection and everything in finding at the local RV supplies is the smaller size.... Any idea where to buy that larger hose or a reducer for the coach to hose connection???

Old style white connections are "Thetford". Now largly superseded by "Valterra". For a quick solution, you just need the proper changeover adapter: Valterra T05-2285VP Universal Adapter. For a much better solution you can cut the Thetford end off your dump pipe and attach a Valterra male connection. Then all the standard dump hoses will work. Search the Forum for more info.

Thanks sooooo much!!! I'll get started on that asap!!😁😁
Most Forum members, when changing from Thetford to Valterra sewer pipe connector, also add a third dump valve. Highly recommended!

Thanks all, got that issue sorted out. Have a slight belt squeal that that im trying to solve. Anyone know the correct belts for the 460 gassed? My manual shows the ones for the diesel and the chevy 454, but not the Ford. Tia.
Take a look at these until you find the one that looks like your accessory arrangement. 1988 ford 460 belt diagram - Google Search (https://www.google.com/search?sxsrf=ALeKk03CjTPez0XeMAyKqRkpd1bAYO6KCA:1620773825370&source=univ&tbm=isch&q=1988+ford+460+belt+diagram&client=firefox-b-1-d&sa=X&ved=2ahUKEwj27vyA3cLwAhWMsJ4KHYExD1IQjJkEegQIChAB&biw=3840&bih=2035)

If I remember correctly there are double belts for the fan and water pump. These belts need to be very tight to keep from squealing.
Thanks, Red tractor.. The manual did mention that as well as belt dressing...
Thanks for all the advice..... But wait.... There's more!! Lol.... Anybody have a parts source for the vintage zip dee awnings? My patio awning needs a new aft rafter assy.
Can find them on the Zip dee web site or talk to Bob(journey roam explore) he just redid his with fabric.
Got hooked up w zip-dee and parts are on the way!! Thanks everyone. Thanks everyone for all the help.

You might check to see if you can get matched pairs-- we could get them for industrial usage but I never tried for automotive --
If you can get them it will make a lot of difference on the belts-- you don't have a loose one and a tight one

I posted elsewhere quite recently that Zip Dee no longer makes the rafter arm end that bolts to the lower roller end die casting.
I had to get a different rafter end that has a hole in it to accommodate the awning roller axle. If you have a shoulder bolt or even a hole on your awning roller head, then you have the "old" style Zip Dee no longer makes.
