|Chevy 454 vs Ford 460||Al Vanek||3-24-04|
I'm looking at buying a class C 1999 Dutchman motorhome with a Chevy 454 engine (and Chasis?) My last coach was a Ford 460. How do they compare? I tow a car and don't want to be short on power and need reliability.
Thanks in advance for your help

|Smokey Yunick said it best: "An engine doesn't know what name is printed on the valve covers"|
They each have their own needs and wants. I'm more of a Ford guy, so I don't know a lot about the Chevy chassis. From what I've read on the board, the Chevy motor is pretty comparable with the Ford motor in terms of power. I defer to the others in terms of what you have to look for to avoid a problem.
Hope that helps!

|I have built a near stock 460 with edelbrock performer and 03310-2 750 Holley a small.218x.228 duration at.050 503 lift 114 degree lobe separation. roller tip rockers 1 3/4 headers dove heads. 425 hp at 5250 and 552 ft lbs torque at 4500 rpm. No head bolts going through the water jackets. No oil drain back problems cause the ford has a drain in the rear top of block. 454 chevy oil has no where to go but to drain back into the middle oil gallery, straight on the crankshaft. Uneven cylinder to cylinder heat wimpy head bolt size and when torquing the heads they distort the cylinder bores and the torque on the bolts can only go up to 65 ft lbs. On a 460 ford they have only 10 head bolts which are way bigger than the little 5/16 bolts on the chevy verses 9/16 ford head bolts. The aftermarket is now full of 460 parts at least 50 aluminum heads to choose.|

|Chevy's Rule. They get Better Gas Mileage, thats a known fact because the way Ford cuts its Valve Angles. Parts are Less Expensive. Fords OverHeat Easier. Had a boat with a Ford engine, ran it in 40 degree water at Topaz Lake, it still over heated. Chevy's are A-Lot easier to work on. Ford always has that one odd ball size bolt or nut on the same part your removing, why do they do that? Transmissions are about the same. Torque-Flite, now your talking Bullet Proof. Chevy has Adjustable Rocker Arms, Ford don't. Ford Odd Fire, Chevy Even Fire, This must be why Chevy's Run, Soother, Cooler, Quieter, Longer. Chevys are Dependable. Never had much luck with Fords, except the 2300cc Pinto Engine's, those were Runners.|

|Sorry to be coming into this discussion so late, but I have extensive experience with both engine series...the big block Chevy as well as the Lima Ford engines. I know what must be done to a Ford to make it run as good as a bone-stock Chevy, and it costs about $2,000.00 more.|
The cylinder heads in every production run Chevrolet big block engine (even the small bore 366s) are FAR superior in their intake and exhaust port configurations than are the cylinder heads on ANY regular production 370, 429, or 460 engines. Ford made an attempt to correct on some of their design errors with the bad heads on their big engines when they made the "Super CobraJet" series, but they went MUCH too far and made humongous ports that actually hurt performance below 10,000 RPM...and let's face it...hardly any engines operated on the street run 10,000 RPMs!
Another thing that Ford did was place a cast-iron pedistal on top of their cylkinder heads onto which is bolted the rocker arm...this is a TERRIBLE idea, and relates to problems after about 50,000 miles of normal usage...the cam wears a bit on the lobes, the lifters wear a bit on their bottoms, and the combined wear makes the Ford engines run like DOGS. Chevrolet engines are made with either pressed in are srewed-in rocker qarm adjustment studs that take into account engine wear...a MUCH better idea for The General!
Also, the way Ford designed the cast-iron cylinder heads on their Lima engines (the 370, 429, and 460s...the ones made in their Lima plant), was with a cast-in runner that goes down the back of the head connecting each combustion chamber. the Air Injection Reator is hooked up to this hole, and it is supposed to help the engines run a bit cleaner. It may very well do that, but it costs each and every Ford engine those heads are placed on at least 25 horsepower and about 30 lb-ft or perhaps even more in torque reduction. One has to trash the Air Injection Reactor, plug up those holes to keep them from leaking outside the engine, and grind the cast-in boss out of every combustion chamber, and THEN it will pick up the horsepower by at least a factor of 50, and the torque by an even greater amount.
Lastly, since 1971 or 1972 Ford Motor Company installed their camshafts in the 370s, 429s, and 460s with a cast iron cam gear that is retarded by at least 4 degrees as it comes from the factory! This was also an attempt to deal with smog problems and new legistlation that called for California engines to run "cleaner." This really puts a damper on performance....BIG TIME!
So, any of you guys that want a big Ford engine that runs like an evil demon (or like any old stock Chevy 454 that comes in a station wagon or other family vehicle), do yourslef a HUGE favor and trash those stock cast iron cylinder head boat anchors, replace them with brand new aluminum heads from Edelbrock (not from Ford..they are more expensive and not as good), and replace your cam gear with one that is cast "straight up" at zero degrees so YOU can set the timing where you want it...and enjoy WELL over 100 horsepower and almost 200 ft-lbs of torque increase. the engine will also run MUCH cooler...cooler even than the 454 Chevies.
This I know from personal experience.

|YOU CANNOT KILL A FORD 460, BUT IF YOU GET A CHEVY, THE 454 IS A GOOD BIG BLOCK ENGINE AND THE ONLY COMPLAINTS I HAVE HAD WITH 454S ARE GAS MILEAGE, BUT THAT IS TO BE EXPECTED. STAY AWAY FROM THE CHEVY 350 LIKE ITS LIFE OR DEATH UNLESS ITS JUST A LIGHTWEIGHT TRUCK AND YOU ARE NOT PULLING BIG LOADS. PEOPLE ARE ALWAYS PUTTING 350S IN THEIR HOT RODS AND TRUCKS BUT IF THE 350 WAS SUCH A GREAT ENGINE, THEN HOW COME YOU CAN GO TO ANY JUNKYARD AND FIND ONE? YOU CAN'T FIND A 454 IN A JUNKYARD HARDLY SO THAT SHOULD TELL YOU ABOUT THE 454.|

|I watched a program chevy vs ford big blocks to get above 600 hp you need to buy a racing crank, rods, piston, roller cam plus lifters and a dart racing heads for a chevy on the ford they just changed out the top end to a trick flow, and a roller cam plus lifters they both used the same 700 cfm holly.|

|Me as a big ford lover a 454 is not bad. But they both have there goods and bads fords are hevy motors but chevys have a better air flow than fords so they can run harder and keep cool longer. so thnks|

|Both engines make plenty of power, so you should be able to tow that car with your RV with the stock 454, but it doesn't take much to build a 460 to the point that you're scared to touch the throttle in even the heaviest vehicles. A common misconception is that Chevy big blocks make more power with less money, but this is simply not true. It depends mainly on how much experience you have with one type of engine. My dad's 460 has run past 300,000 miles, nearing 400k, and still runs smoother than the 454s I've dealt with, and we're talking about a very mild 460. It's also gotten us far better gas mileage than the 454s we've encountered. I like either one, but these are simply facts from experience. Another common mistake is that people think Fords overheat easily. My dad uses the stock radiator in his van, but he's have never had his engine overheat, even when running past 6000 rpm. I, nor my dad, haven't even been able to get a 454 to 6000 rpm, and they overheat every time I pull a feather weight load. My experience has tought me that you can't trust those Chevy nuts claiming that they have problems with Fords, because Fords just don't stop going. Don't listen to the stupborn Chevy guys. Drive your 460 until it won't drive anymore, if you live long enough for that to happen.|

|I am considering two bounder motor homes 34'almost the same year 91, 92 and equal in most all ways except one! that is one has the chevy 454, and the other the ford 460 the chevy has around 85K and the ford 60K. The chevy owner states that he only gets about 6 mpg and the ford owner claims around 10. Big difference. I have also seen a lot of coaches that have rebuit engines at both these miles. Which is the best choice? what experiences do others hove with these different engines and drive trains...thanks|
