I have a 1986 Ford E-350 Van with the 460ci Carb motor that

Customer Question

I have a 1986 Ford E-350 Van with the 460ci Carb motor that caught fire,top of motor melted...spark plug wires, cap...and just about everything on the top of the motor and just had the carb rebuilt and they forgot to set the bowl gasket correctly....leaked and caught fire...I have 100k on the motor/trans...
Option #1 Is a 1985 e-350 van 460ci the same block? It too is a E-350 van....
Option #2 I also have a 1979 E-350 (Federated-49 state) 460ci with only 63k miles out of a motorhome...and I think this engine has more horse power...than either my 1986 or the 1985
Will I be able to use either long block?....to fit my 1986 e-350....

ASEMaster35yrs :

First to answer your question, you can use either block, they will interchange, however, if the engine that is now in it is good, all you would really need is the perifials, carb, wires, vacuum hoses, rubber hoses, sensors and sending units and anything that was damaged in the fire. How long did the fire burn? If it burned to the ground you would be better off with another vehicle entirely.

ASEMaster35yrs :

Usually the worst part of having a fire is the wiring, not the engine itself.

ASEMaster35yrs :

Frankly, you would be better off with another vehicle since most of your problems will be electrical.

Customer :

There seems to be a difference in the heads that are on these 460ci blocks.....somewhere I read that the 1985 to 1992 has both 1/2" & 9/16 threaded holes for exterior engine mounting stuff....A/C comproessor, Alternator brackets....so my 1979 E-350 only 63k mile may not work...when looking at long blocks...the year range is 1979 to 1992....with carburator years being 1979 to 1987 and 1988 to 1992 fuel injection...and the other issue is the crank-dampner pulley...internal to external..... Are cranks are different inside? and does a 1979 460ci block make more horsepower than 1985 on? I mention that this van has a special body on it....so it's worth keeping...

460 Blocks

There were two basic blocks, 1968 to 1978 with an internally balanced crank and 1979 to the end of production with an externally balanced crank.

Up until 79 the 460's were internally balanced. The EFI models, starting 88 - 97, have a different intake port arrangement, but that only affects the intake and heads. The EFI cylinder heads have a different pattern for the intake to cylinder head from the carb versions. The fuelie heads have high squarish exhaust ports. Earlier engines have oval ports.

On the D9 block (1979), ford made the cylinder bores longer and went to an external balance crank configuration. The cylinder head to block bolt pattern has always been the same. The only difference could be just the hole for the mechanical fuel pump is not machined on EFI versions.

The only real differences between the car and truck 460 are the exhaust manifolds and the oil pan... car is front sump and truck is rear sump, and the car got emissions crap before the truck.

 

Please note: the last FoMoCo passenger car to use a 460 was the 1978 Lincoln Town Car. The 460 engine was not available for passenger cars in 1979.

The flywheels, and vibration damper are casting number specific. D9TE-6015-AB uses a weighted spacer, D1VE-6015-AB does NOT!

 

>>> Taken directly from the 1973/79 Ford Light Truck Parts Catalog:

 

1973/79: D1SZ-6375-A .. Flexplate = use with D1VE-AB

 

1979: D9TZ-6375-A .. Flexplate = use with D9TE-AB

======================================

 

1979: D9TZ-6316-B .. Vibration Damper = Use with D9TE-AB

 

1973/79: D4VZ-6316-A .. Vibration Damper - Use with D1VE-AB

 

Of all 460 heads the "DOVE" were the best for compression and exhaust port flow. The rest do not flow well, the exhaust ports are very restrictive, they are low compression and they are incredibly heavy. They should never be considered for use in a high performance buildup.

 

Blocks were produced at Flatrock until the introduction of the D9TE block for 1979 when production was moved to Cleveland Cast Products till the end of production. What is interesting is how each foundry used unique tooling to produce the blocks each of which having unique and often special features. For instance, the DOVE-A blocks produced in the Dearborn foundry are the only ones cast with extra thick main webbing to allow for the factory installation of 4 bolt main caps. Not all of the DOVE-A blocks have 4 bolt mains but they all have the provision for them. The D9TE blocks are cast with a cylinder wall that's .250 longer than other production blocks and this is an interesting feature. It's not known why the factory changed this but it is certainly a plus if long strokes are being run, giving the piston more support at BDC. (4.500 stroke 6.700 rod combinations work fine in all production blocks) SVO blocks also have this feature. Not to be left out, the D1VE blocks from the Michigan/Flatrock foundry are the most numerous and they were used in 429 and 460 production from about 1971till 1978.
